Quarterback: Patrick Mahomes, Kansas City Chiefs (23 years old as of Sept. 5). No need to get too cute out of the gate: Mahomes is the clear choice under center after an MVP campaign that rewarded fans with more than just bursting box scores. Yes, the Chiefs passer notched the kind of statistical feats that make keyboard-facing number bods hot and bothered (for starters, his 134.2 passer rating from a clean pocket marked the highest qualifying single-season mark in the 13-year history of Pro Football Focus) while tossing for 5,097 yards at 8.8 yards per attempt with 50 touchdowns and 12 picks. It's about how the newbie starter did it, though, beguiling cover men and puzzling even the smartest chess players with a fast-arriving ball that left defenses out of position all season long. With Mahomes at the helm, the Chiefs were an explosive beast with a knack for raining down points like an NBA team on a 24-2 run. It's fair to expect Mahomes' numbers to regress some in 2019, but that doesn't diminish his physical gifts. Cleveland's Baker Mayfield (24) would be my second choice here -- with so much to like -- but Mahomes is the unquestioned leader today.
