Three Underdog picks for Monday
Player | Projection | Our pick |
CeeDee Lamb, DAL | Anytime Touchdown | Yes |
Tanner McKee, PHI | 199.5 Pass Yards | Lower |
Junior Caminero, TB | 1.5 Hits + Runs + RBIs | Higher |
The lights will be too bright on Monday night for McKee for him to cross the 200 yard threshold, even against this Cowboys defense. With the Eagles offense limited, there will be plenty of chances for Lamb to get in the endzone when Dallas has the ball. Game 3 of the World Series is also Monday night, and Junior Caminero is poised to swing the Rays back into the series.
