Then, you don't know this fanbase very well. Last year, Howard Simon posted an article around October/November where he said "we need to seriously start talking about Tyree Jackson if Allen doesn't show improvement down the stretch." That's a long-time member of the local media who openly stated that he was willing to give up on Allen after 1 year (granted, Howard hated the Allen pick and went so far as to say that he "didn't want to talk about it" on the morning after last year's draft).
One interception from Allen in pre-season will be enough to have fans and media going "oh, boy. who are the top QBs coming out in 2020?"
