College football's first two weekends were full of upsets and surprises. This week's games will attract even more bets from average Joes and professional bettors.

No. 3 Clemson is a field goal favorite over No. 14 Louisville, No. 24 Florida is favored by 4.5 at home against No. 23 Tennessee, and top-ranked Alabama is a 28.5-point favorite against 2-1 Colorado State in a game that has seen the line move up already.

With so many eye-popping games and so many college football odds changing, you'll want to know to what the "sharps" are picking. They're the guys who make their entire living betting sports. Ignoring them means throwing away your money and banking on luck.

SportsLine tapped into its Vegas sources to see who the pros are on and what they found out was shocking: Pro bettors are all over Sam Darnold and USC at home against Texas. Their max bets on USC moved the line from USC -14 all the way to -17. Why is that shocking? Texas has scored 97 points in the first two games under offensive mastermind Tom Herman and just shut out San Jose State 56-0.

BookMaker doesn't expect the line to climb above 17.

Similarly, The Greek Sportsbook took sharp money on USC -15.5, but other professionals backed Texas when the line hit 16 and then again when it hit 17. By Friday, the line had receded to -15.5 at several books.

The pros were also jumping on Boston College, now a 13-point home dog to Notre Dame. The Fighting Irish lost last week in South Bend to Georgia even though the Bulldogs were without starting QB Jacob Eason. Pros aren't buying a two-touchdown Notre Dame victory even though BC lost by 24 to Wake Forest last weekend.

And the sharps aren't a believer in Jim Harbaugh and Michigan this week. Instead, they've been putting their money on Air Force, causing the line to dip from Michigan -25.5 to -23.5.

Speaking of Michigan, pros and average Joes alike pounced on the under in their game as well, sending the total diving more than a touchdown from 57.5 to 50.

Sharps were hammering the under on Saturday's Tennessee vs. Florida game, causing the total to drop to 48.5. Pro money was split evenly on each side against the spread, but one thing was clear: Pro bettors loved this top-25 battle to go under.

Pro bettors are also all over one side of the Clemson-Louisville game, causing bookmakers everywhere to change their college football odds.
