Best bets for Saturday

SEC rivals square off in Week 4 college football action as No. 11 Oklahoma hosts No. 22 Auburn at 3:30 p.m. ET. Both teams are 3-0 on the season and thriving with new starting quarterbacks, with Sooners quarterback John Mateer emerging as a Heisman Trophy favorite. Meanwhile, former Oklahoma recruit Jackson Arnold prepares to lead the Tigers against his former team. The SportsLine Inside the Lines team model, which simulates every college football game 10,000 times, has issued an 'B' grade for Auburn +6.5 as the Tigers not only win in the majority of simulations, but the team covers in well over 50% of sims.

In-conference action continues with a Big Ten battle between No. 9 Illinois and No. 19 Indiana. Both sides enter Week 4 at 3-0 and are coming off of blowout wins, which should make them extra eager to pummel each other since each of the last two head-to-head meetings were decided by a field goal. The Hoosiers have won four of the last five meetings, but the Fighting Illini are covering the spread in well over 50% of simulations by the SportsLine projection model.

Responsible Gaming with BetMGM

Bettors should always practice responsible gaming by not chasing losses and betting within their means, and BetMGM offers assistance for this issue, such as a live chat feature, various gaming limits and contact information for helplines like 1-800-GAMBLER, which bettors can call or text 24/7.
