I think Tommy or any QB is going to be as good as the OL allows.
Babak is new to C. How many times did the timing of a play get disrupted bc of a high snap. That's an extra second or so to get the ball to Otis or find a received, and with a relatively porous line that second means a lot.
Any word on Lotusz? He was the top C in the fall.
And all of those calling for heads, how many players are gone to the transfer list as soon as that happens? Then you have another 3-5 years of a rebuild at which point the same chorus cries out for a new Coach. Rinse/repeat.
