Quietly, Brissett has:
4th most passing TDs in the league
3rd least interceptions
24th least pass attempts
I think a lot of the 'game manager' talk is just people latching on to a term and using it so they have something to say.
More accurately, Reich's game plan produces a different set of expectations from the Quarterback position than we see frequently. JB so far is filling the role. If Vinny had made one of his two missed FGs, or made his extra point In week 1, we would be a 5-1 team and the conversations about us would be different.
There's some interesting poultry going on: How much is Reich changing for Brissett and how mush is Brissett changing for Reich?
