I get it, and there is a certain level of plausible deniability in the "how would he know" category.
I just find it almost too convenient that Kromer's "story" and the buyer's remorse story came out on the same day in the same article. And like you said, one is being frustrated at the QB's mistakes and the other is, we really screwed up with keeping this guy. Which are totally different animals in how they come across.
Sure. But there's bad reads then there's "he's killing us." There's admitting others' mistakes and then there's blaming. IMO, it falls in the second category.
