Strength of schedule has become more important than ever before in college football. With the College Football Playoff selection committee choosing four teams to compete for the national title every season, it's not just important to win as many games as possible, but you want to beat the best teams possible to help boost your resume.

Which is why we've seen Power Five teams scheduling more and more Power Five opponents in their nonconference games in recent seasons. Some conferences, like the Big Ten, have even adopted policies stating that they don't want their schools scheduling any more games against FCS school. And then there are conferences like the Big Ten, Pac-12 and Big 12 that have moved to nine-game conference schedules rather than the traditional eight.

And they've done all of this in an effort to improve their strength of schedule. To help ensure that their best teams have strong resumes worth considering for the CFP at the end of the season.

It's with all of this in mind that I decided I wanted to figure out which teams were playing the toughest schedules in 2017 before the season even started. Now, there's no perfect way to decide strength of schedule, but I found a method I believe works well enough. I went through each Power Five team's 2017 schedule and rated teams based on how they've performed in my own personal rankings -- the same mathematical rankings I use to compile the Fornelli 50 and Bottom 25 -- over the last three years. This gave me a baseline. A baseline I then tinkered with a bit.

It's one thing to play Alabama, but are you playing them in Tuscaloosa? At a neutral site? Are you coming off a bye?

These are all variables I considered and weighted a bit. Road games are always more difficult, and having to play a team without having a Saturday off for the last month can wear on your team as well.

As no formula is perfect -- teams always surprise you, whether it's by exceeding expectations or failing to meet them -- I averaged each teams' individual ranking based on the last three years rather than just last season. This should give us a good idea of what to expect each team will be facing in the 2017 season.

Here's how things break down for the Big Ten in 2017, from most to least difficult.  

Big Ten Strength of Schedule Rankings
1
This one really shouldn't come as much of a surprise. Not only does Michigan State play both Western Michigan and Notre Dame in its nonconference schedule, but it also plays in the Big Ten East where it must contend with Ohio State, Michigan and Penn State. Of those three opponents, only Penn State will be coming to East Lansing. Also, while Michigan State avoids both Wisconsin and Nebraska out of the West, it still must go on the road for Minnesota and Northwestern while getting Iowa at home.
2
Yes, Purdue's schedule strength is helped out by not having to play Purdue, but there are plenty of other factors contributing to its schedule being ranked so highly here. Not only does the season open with Louisville in Indianapolis, but after a home date against Ohio, the Boilermakers hit the road to take on Missouri. That's two Power Five opponents in three nonconference games. The Boilers also draw Michigan from the East while having to play Wisconsin, Northwestern and Iowa all on the road. The good news is the home slate does provide winnable games against Minnesota, Illinois and Indiana.
3
Illinois' schedule is difficult to judge on the surface. The nonconference includes two strong Group of Five opponents in Western Kentucky and South Florida (in Tampa), but both of those programs will be led by new coaches this year, so it's possible they won't be as strong as they have been recently. Things don't get a whole lot easier in the Big Ten because while the Illini may get Rutgers and Indiana from the East, they also get a road trip to Columbus to take on Ohio State. Also, a couple of their more winnable conference games against Minnesota and Purdue both come on the road, making those wins significantly more difficult to achieve.
4
As if playing the East Division powers wasn't difficult enough, Maryland starts its season with a road trip to take on Texas. Its cross-divisional draw in conference play includes road trips to Minnesota and Wisconsin, while another tough team in Northwestern will come to College Park. The good news is that both Indiana and Rutgers come to Maryland as well this season, and those two are looking like a couple of very important games in the Terps quest for bowl eligibility.
5
Michigan certainly has one of the more impressive nonconference slates in the Big Ten, as it will open the season against Florida in Texas and follow that up with games against respectable foes in Cincinnati and Air Force. The Big Ten schedule is not as difficult as it could be, though, as the Wolverines will get to face their two biggest rivals -- Ohio State and Michigan State -- in Ann Arbor. Still, there are road trips to both Penn State and Wisconsin on the schedule, and neither of those will be easy.
6
Nebraska's nonconference schedule is bolstered by a road trip to Autzen Stadium to take on Oregon in the second week of the season. Arkansas State and Northern Illinois should provide a challenge themselves, but nothing like what the Huskers will face with the Ducks. In conference play, the Huskers didn't get many favors from the schedule makers, as they draw both Ohio State and Penn State from the East. Luckily it's offset a bit by Ohio State having to come to Lincoln and a home date with Rutgers as well. Nebraska will also get to face two of its divisional rivals in Wisconsin and Iowa at home as well.
7
While Penn State will play Pitt in September, having both Akron and Georgia State on its nonconference schedule as well gives the Nittany Lions one of the easier nonconference slates among its Big Ten brethren. That's all offset by its conference schedule, though, as the Nittany Lions not only have to play the East powers but also get Iowa, Nebraska and Northwestern from the West. Both Iowa and Northwestern will be road games.
8
Iowa is in a similar position to Penn State in that it has a relatively weak nonconference schedule (Wyoming, at Iowa State, North Texas), but finds itself with quite a gauntlet to manage within the conference. Iowa gets no breaks in its cross-divisional draw as it will have to play Penn State, Michigan State and Ohio State out of the East this season, though only the Spartans on the road. Within the division, the Hawkeyes have to hit the road to take on Northwestern, Wisconsin and Nebraska. All in all, it's one of the most difficult road schedules within the Big Ten.
9
The Buckeyes get Oklahoma in Columbus this season, which boosts a nonconference schedule that also features home dates with Army and UNLV. Neither of those latter two should provide much of a challenge to the Buckeyes. Things get more difficult in conference play. The Buckeyes will hit the road to play Nebraska, Iowa and Michigan this year. Other road games against Rutgers and Indiana are much more manageable, and the home slate is favorable even with Penn State and Michigan State on it.
10
The Rutgers schedule is one of extremes. It includes games against half the 2016 College Football Playoff field as the Knights open the season against Washington and get Ohio State later in the year. The silver lining is both teams come to New Jersey. On the flip side, two of the three teams Rutgers must play from the West happen to be the West's two weakest teams in Illinois and Purdue. What really drags this schedule down, though, is the fact that Rutgers is the only Big Ten team with an FCS opponent this season as it will play Morgan State.
11
While we shouldn't take anything for granted when it comes to college football's Chaos Team, the Hoosiers have a very manageable nonconference schedule. They get Florida International and Georgia Southern while going on the road to take on a Virginia team that's been one of the weakest in the ACC. They're also lucky to get both Ohio State and Michigan in Bloomington, though that Ohio State game will be the season opener. From the West, Indiana gets Wisconsin, but the Badgers come to Bloomington, and the two road games are winnable ones against Illinois and Purdue.
12
Wisconsin has one of the easier schedules in the Big Ten this year, but after the one it played last season, we'll have to forgive the Badgers for it. Nonconference games against Utah State and Florida Atlantic shouldn't provide much resistance, though a road trip to take on BYU could get interesting. After that, the Badgers find themselves with a very manageable road slate in the conference as they'll play Nebraska, Illinois, Indiana and Minnesota outside of Camp Randall. Aside from Indiana, the cross-divisional draw features Maryland and a game against Michigan in mid-November that could have major consequences for both teams.
13
Northwestern's nonconference schedule includes three teams that combined to go 13-23 last season in Nevada, Duke and Bowling Green, though at least Duke will be a road game. While the cross-divisional draw includes both Penn State and Michigan State, both teams will be coming to Evanston, as will other foes like Iowa and Minnesota. The toughest tests will likely be road trips to both Wisconsin and Nebraska.
14
The Gophers will not be rowing their boat through the choppiest of waters this season. The nonconference features winnable games against Buffalo, Oregon State and Middle Tennessee, while both Nebraska and Wisconsin head north to Minneapolis this season. The toughest game on the slate is a road trip to Ann Arbor in early November.
