Well... I would not go as far as saying he was a wasted pick. Jackson is a good prospect. As far as getting on the field this year much, I tend to agree with you, though I think there's still a chance he can provide something on obvious passing downs...
He's a rookie... He was Drafted at a position where the Bills already had Groot, AJ, 2024 5th Rd pick Solomon, plus UFA's Bosa and Hoecht... So it's pretty crowded... Now with Hoecht down he's got a chance... He's very athletic for his size, but he is high-cut with skinnier legs so he's going to have to get stronger in his lower half...and that's going to take some time...probably a full off season. He was Drafted after they signed Bosa and Hoecht, so I think they took him more with 2026 in mind tbh... Just my take on it...
