Former No. 1 overall pick Caleb Williams will play his first meaningful game under new head coach Ben Johnson when Williams, Johnson and the rest of the Chicago Bears battle the NFC North rival Minnesota Vikings on Monday Night Football at Soldier Field. Last season Williams had an uneven rookie year, finishing with a 87.8 passer rating that ranked 24th in the league. But the arrival of the 39-year-old Johnson, who has been the offensive coordinator of the Lions' potent attack the last three seasons, is designed to get the most out of Williams. For Monday, Williams' passing yards prop has been set at 218.5 yards. Kickoff for the Chicago-Minnesota game is set for 8:15 p.m. ET.

Before you play a side on any player prop for Week 1 of the NFL season, you need to see what player prop expert Alex Selesnick has to say.

An experienced poker player, Selesnick (aka PropStarz) specializes in NFL, MLB and NBA prop betting, where he implements a combination of research, statistical analysis and mathematical modeling. Since joining CBS Sports in 2021, he is 979-780 on all picks for a profit of $2,643.

For Week 1, Selesnick has studied the data and has identified his six best player props. We can tell you that he is taking Under 112.5 total rushing and receiving yards (-113) for 49ers running back Christian McCaffrey against the Seahawks. "C-Mac appeared in just four games last year and after a seemingly healthy offseason just popped up on San Francisco's injury report with a calf issue," Selesnick told SportsLine.

However Selesnick has five other best bets for Week 1. One of those is a play on a "workhorse" running back facing a "subpar" rush defense. You ABSOLUTELY NEED to see his picks before locking in any of your own.
