Week 7 of the 2018 college football season is already here and teams across the country are hunkering down for the always-difficult conference portion of their schedules. Surviving eight- or nine-game conference slates requires depth and persistence, and wagering on those matchups requires exactly the same. With multiple Top 25 showdowns and 13 Power 5 conference matchups featuring spreads of seven points or fewer on Saturday, turning a profit with your Week 7 college football picks and predictions could be a challenge depending on who you listen to.

Who better to help than CBS Sports college football analyst Barrett Sallee? He is a true insider -- a CBS Sports HQ personality, SiriusXM host, Heisman voter and one of the top CBS Sports experts picking games against the spread -- and his college football expert picks have brought in some huge returns.

Last season, he began giving his best bets to SportsLine and the results were impressive, as he went 28-18 on against-the-spread picks. He also correctly predicted Arizona (+2.5) winning outright as an underdog against California in Week 6. Anybody who has been following him is way, way up. 

Now, Sallee has studied a loaded Week 7 college football schedule and revealed his top three college football picks over at SportsLine. 

In a rematch of last year's epic AAC title game, we can tell you that Sallee is backing UCF (-4.5) on the road over Memphis.

Sallee knows Memphis is undefeated at home this season, outscoring their opponents 232-85. The Tigers have an extremely explosive offense that features Brady White, who's thrown for 1,158 yards and 13 touchdowns at home this season, and the nation's leading rusher, Darrell Henderson. However, the Tigers are just two weeks removed from an embarrassing 40-24 defeat at Tulane. 

Meanwhile, the Knights enter Saturday's showdown on an 18-game winning streak. UCF is also a perfect 11-0 against the Tigers since making the move up to the FBS level. Despite their impressive streak, the Knights have covered the spread just once in their last five games on the road against Memphis. 

However, Sallee expects White will try to force the ball into tight windows against a stingy UCF defense, which should be a major factor in the Knights covering. Confidently lay the points and lock in UCF covering the 4.5-point spread against Memphis. 

Sallee has also found two other games with huge flaws in their lines, and is backing an underdog to not only cover, but to pull off a shocking upset.
