Patrick Mahomes, QB, Kansas City Chiefs
It's usually not wise to expect big things from a first-year starter at quarterback, but I'm still going to plant my flag with Mahomes because of Andy Reid's track record in helping QBs succeed. Mahomes, the 10th pick of the 2017 draft, threw for 284 yards and an interception in his one and only career start -- the final regular-season game of last season -- but people inside the Chiefs' building say Mahomes' growth during the season allowed the team to feel comfortable enough to trade away Alex Smith this offseason.
