When it comes to college football, there are few who deserve the "expert" tag quite like Barrett Sallee. The CBS Sports writer and analyst hosts shows on SiriusXM College, writes for CBSSports.com and appears regularly on CBS Sports HQ as well as countless radio shows across the nation as a guest.

Sallee debuted with SportsLine in 2017 and has delivered in a BIG way. Over the past two-plus years, he is 85-61 in his popular best bets column. Anybody who has been following him is WAY UP.

Now, he's turned his attention to the Week 4 odds from Caesars Sportsbook (see the latest college football lines for each game this week on our college football odds page) and is revealing his three top plays for Saturday. A parlay on these three picks would return around 6-1. 

We can tell you Sallee is backing Notre Dame (+6.5) against Wisconsin in a noon ET kickoff from Soldier Field in Chicago. 

"Starting quarterback Jack Coan will know exactly what to expect from the Badgers defense after beginning his career in Madison," Sallee said. "Fighting Irish star safety Kyle Hamilton will prevent the Badgers from stretching the field deep and the front seven will shut down the Badgers rushing attack enough to get a cover."

Sallee has also found two other college football picks he loves, including a must-see play in a big game where he says the underdog is primed to pull off an outright upset! You ABSOLUTELY need to see who it is before locking in any college football picks.
