After 6 offensive coordinators and how many offensive line and wide receiver coaches, these things have been completely consistent:
inconsistent offensive line play, including ability to deal with looping defense lineman
a LOT of bunch screens or runs to the short side of the field
the stupid wildcat direct snap where the QB lines up at WR, wasting a down
slow developing pass routes
predictability where the defense is able to often guess what's coming
3rd down conversion struggles
underdeveloped QB development after multiple years of starting
Even in the Joe moorehead era, up to half time of the Minnesota game, the offense looked exactly the same as the J Donovan era. There was a ton of heat on Franklin then, and after halftime it seems he let go, and the rest of that season is (positive) history
I feel bad for Allar. He is headed on the same trajectory as Hackenberg and Clifford, underdeveloped and misused.
