Also, the Bills started and played 2 UDFA rookies from Alabama that had an impact in the game. Neither guy was a star at Bama either. That should give a sense for the level of talent that they are pumping out.
The reality is he’s pretty much the same guy. He’s a guy that they probably should have used to stretch the field all year. He was a 5 star recruit so he wasn’t some unknown. Foster is the same guy that he’s been for years. He’s a big play threat that struggles to track the ball. The month on the PS didn’t change him. The opportunity changed him.
