Granted, these are not traditional stats, but it's an interesting way to try to single the contributions of the QB out from the contributions of everyone else.
Ranked by stats on the following categories:
Most valuable
Least valuable
Most aggressive
Least aggressive
Most accurate
Least accurate
Most Valuable:
3. Jameis Winston, Tampa Bay Buccaneers
QB EPA: plus-38.4 (13th)
Team EPA: minus-87.9 (24th)
QB-added value: plus-126.4
Winston's third season was not great, but he still finished 13th in EPA despite missing three games to injury. The bigger problems in Tampa Bay were a poor running game, as Doug Martin failed to crack 3.0 yards per carry for the second year in a row, and the defense finished 32nd in DVOA. Out of the 28 quarterbacks/teams studied, Winston and Cleveland's DeShone Kizer were the only two who had a defense (26th) and special teams (21st) both ranked 20th or worse in EPA last season.
Most Aggressive:
3. Jameis Winston, Tampa Bay Buccaneers
2017 ALEX: Plus-2.9
Winston joins Wentz and Rodgers as the only quarterbacks to throw their average third-down pass more than 10 yards down the field last year. This has been a fairly consistent part of Winston's three-year career in Tampa Bay. He finished fifth in ALEX in 2016 (plus-3.0). The addition of DeSean Jackson did not really help the offense last season (plus-11.4 ALEX, but a 25 percent conversion rate), but Winston still has a deep receiving corps to work with.
Most Accurate:
3. Jameis Winston, Tampa Bay Buccaneers
C%+: 4.5 percent
Winston actually set a lot of career-highs in passing in 2017. One of the main reasons his C%+ was so high is that he threw the deepest passes in the league, at an average depth of 10.3 yards. He also was efficient with almost every player he targeted, save for departed running back Doug Martin (minus-20.7 percent C%+) and deep threat DeSean Jackson (minus-0.1 percent C%+). With O.J. Howard and Chris Godwin entering their second seasons, Winston could be poised for even better numbers once he returns from serving a three-game suspension.
