Three Underdog picks for Thursday
Underdog’s primary game method is where users pick higher or lower on player stat projections. Here are my favorite picks for the Thursday Night Football matchup.
Player | Projection | My pick |
Drake Maye, NE | 249.5 Passing Yards | Higher |
Caleb Willams, CHI | 19.5 Rushing Yards | Lower |
A.J. Brown, NE | 69.5 Receiving Yards | Higher |
Look for this to be the breakout game for the Maye to Brown connection that the Patriots envisioned when trading for the former Titans and Eagles star receiver. The Patriots also showed great defensive acumen containing Josh Allen’s scrambling two weeks ago, and I think they do the same to Williams and negate his threat as a runner.
