Kansas City Chiefs: Patrick Mahomes, QB. The Chiefs' new QB1 took the team's Ferrari-like offense on an impressive spin in K.C.'s dress rehearsal against the Bears. Mahomes completed 18 of 24 passes for 196 yards and a score while throwing the ball to a handful of explosive playmakers on the perimeter. No. 15 not only displayed exceptional range and arm strength pushing the ball down the field and to the sidelines, but he showed tremendous discipline working the short and intermediate routes available against the Bears' coverage. With Mahomes content to spread the ball around to a number of pass catchers, defensive coordinators could have a tough time slowing down the Chiefs' offense with the young gunslinger at the controls. Grade: A-
