You must have forgotten that Titans game and just checked the box score. Boom Herron was the starting RB, backed up by Boobie and Cierre Wood. Sammy was out; Woods had 1 catch. TT played with absolute trash, on the road and took the game over with his legs in the second half. He was the only playmaker on the field and did exactly what he needed for his team to have a chance to win. That's a game manager performance.
What was his job in the second half of that Raiders game?
Disagree on the Titans game, he was bad. 10 completions, 109 pass yards, 75 rushing, 4 sacks, 24 minutes TOP, 4-12 on 3rd downs, had 2 scoring drives and won a game scoring 14 points(defense had more to winning that game than anything else), had 4...3 and outs, 1 drive of 4 plays, 1 drive of 5 plays and 1 drive of 9 plays. If that's a game manager to you, then our definitions differ a whole lot.
I know that you picked the Raiders game because it fits your never-ending narrative but intuitively I will bet that the Bills have been one of the better teams in the league once they got the lead? I haven't looked at it comparatively but their elite ground game is crucial to holding leads.
