Blake Corum Longest Rush over 12.5 yards (-120 at BetMGM, fine with over 13.5 -108 at FD or -110 at 365) Last week I talked about fading Corum in this market, especially without RG Kevin Dotson who is a much better run blocker than his backup, Justin Dedich. Now that the Rams are likely to get Dotson back, we should be looking back toward Corum's over. Getting Dotson back is huge for his yards per carry, since Corum gets the plurality of his runs to the right side. Any run to the right of middle now has a better shot to get busted for a big gain, and that's especially true against a putrid Bears run defense that ranks 28th in rush DVOA. Corum's median longest rush per game since his role increased twelve games ago is exactly 12.5 yards, but we'd certainly expect this to be a spot he goes over that given the matchup and expected return of Dotson. Tracking at 13.5 since only MGM has 12.5 at the time I'm tracking

Betting Highlights
Favorite Bet of All-Time
I bet on my favorite driver Kyle Kirkwood at 20-1 to win the Long Beach Grand Prix. I went to the race and watched him win it in person for his first career IndyCar win. It was the first time I watched him race an IndyCar in person, so I'm officially his good luck charm.
