The Week 6 college football schedule features three matchups between ranked teams, as No. 4 Ohio State hosts No. 25 Michigan State, No. 19 Michigan battles No. 14 Iowa and No. 10 Florida takes on No. 7 Auburn. Those three high-profile conference matchups could have lasting implications for league titles and the College Football Playoff. However, if you're making college football picks, you're not necessarily looking for the biggest game; instead, you're looking for the top college football best bets. If you can get on the right side of the number, No. 24 SMU (-13) vs. Tulsa can be just as valuable as a battle between top-25 teams. Having a reliable set of college football expert picks to lean on can be key, so be sure to see the Week 6 college football best bets from SportsLine's Barrett Sallee.

He debuted with SportsLine in 2017 and has delivered in a big way, posting a winning record in his weekly best bets column since that point.

Now, he has turned his attention to Week 6 and is sharing his most confident college football expert picks over at SportsLine. We can tell you Sallee is backing the under (48) in Saturday's SEC showdown between No. 7 Auburn and No. 10 Florida.

Auburn is a 2.5-point road favorite, but the two sides have each covered the spread five times in their last 10 matchups. However, the two teams haven't combined to score more than 44 points their last four meetings. Two strong defenses taking the field once again on Saturday make the under the play once again.

Florida has given up just 44 total points in five games this season (8.8 per game, which ranks fifth in the nation) on the back of a monstrous defensive line that allows just 2.9 yards per carry. Meanwhile, Auburn ranks 22nd in scoring defense (17.2 points per game), as the Tigers only allow 3.1 yards per carry. Both offenses are dependent on running the football, but both will be rushing into the teeth of strong defenses. As a result, Sallee is comfortably backing the under on Saturday.

Sallee has also found two other college football picks he loves, including a shocking underdog he's expecting to win outright in Week 6. You can only see who he's backing at SportsLine.
