Here are my favorite plays on Underdog Fantasy for today’s football games:

Player

Projection

My pick

Bijan Robinson, ATL

18.5 Longest Rush

Higher

Kenneth Walker, KC

Anytime Touchdown

Yes

Dak Prescott, DAL

274.5 Pass Yards

Higher

Robinson breaking a big run on Atlanta’s home turf feels like a solid pick against an unintimidating Bears D. Walker to score a touchdown feels like and automatic pick; he has slotted in seamlessly in KC after Seattle let him slip away. Prescott is the diciest proposition here, but he’s been locked in this season and the Cowboys and Packers look destined for a shootout.
