Almost 25 years into the job, Reid still isn’t immune to clock miscues or slow starts, and his post-Philadelphia renaissance certainly has something to do with Patrick Mahomes. But he always gets the best out of his QBs, and that’s never been more apparent than with No. 15, whose backyard style blends perfectly with Reid’s fancy for trickery. He could stand to put the pedal to the metal earlier (both in games and on the schedule), but it’s astounding how unfazed his entire team has become as he’s extended his stay in K.
