Take this for what it’s worth because it’s coming from Weis. I’ll preface this by quoting him as saying that Brady was errant and that it’s one of the reasons why they lost. So he didn’t absolve Brady. But he concentrated on the difference in YAC. Goff’s receivers caught the ball and would rip off 20-30 yards in YAC at the blink of an eye. The Bucs don’t tailor their offense to that. Weis was hammering home how important that is to any offense - especially one with a LT who was gimpy and one of the better guards in the league out. He was critical of Fournette for dropping those balls because he had real estate in front of him.
IMO, the reason for the lack of YAC in their offense isn’t only on the play calling, but that’s a large part of it. With their OL piecemeal, teams like the Rams can get away with rushing 3-4 and dropping everyone else while still getting home. I’d suspect that will change once Marpet gets back and anchors that unit up front. But with that many guys in coverage, there wouldn’t be many real YAC opportunities anyway.
