Bulldog was really high on Jackson and want the Bills to draft him back in 2018 so he's always been pro Jackson. Its getting pretty bad though with how he keeps defending him and calling out teams for not wanting to talk to him. I think a little bit of it has to do with the sunk cost fallacy. He's spent so much time being a fan that he just can't be objective. It's hard to say "I was wrong."
One thing that drives me mad whether if its Bulldog or other pundits is how they throw around that he is an MVP but never mention that it was four years ago and he hasn't finished that last two seasons. They also never bring up his 1-3 playoff record.
