He's a big reason why the running game works as well as it does.
47 TDs, 15 turnovers, 1000 yards rushing is far from terrible. the Bills are 15-14 when he starts. If the defense was just average, the Bills would have been in the playoffs in 2016. TT is so bad yet him and Watkins were one of the best duos in 2015. How many games in 2016 did the Bills field the worst WR corp in the NFL when Watkins and Woods were hurt.
This roster was built to be a strong running team, and TT was brought in to manage it. This roster is not built for shootouts. The defense was the main problem.
