DJ is fine, it's the offensive line that's the source of the problems on offense. DJ is only in his nineteenth game, has never had a great supporting cast around him starting with the OL, and it's way too early to judge.
Don't get me wrong, if we win the Trevor Lawrence sweepstakes, I think you take him, but if not, I see no reason to start all over with another rookie QB prospect. Lawrence is generational. Any other prospects in the 2021 draft will just be re-doing the last two years.
