I know it’s fun to make the answer 110% black and white... and I agree the overwhelming majority lands on marcell...
but the truth is th is a lot of dudes in this league exist on the fringes of what you and I would consider acceptable. Lots of bad backgrounds, enabling, etc... in their pasts.
A guy like Marcell, even short of his full potential, is still a world class talent. As an organization you have choices in how you manage those situations. As an organization the bills have had a lot of disfunction through the years. I feel like the organization managed to hit the worst on both sides by giving him the biggest financial commitment possible with little team leverage, while also giving him little structure to maximize his talents.
in turn the new regime shipped him out quick eating a TON of cap for a player I think we probably could’ve reached well enough to make the 2 year plan worthwhile (maximizing the contribution received per dollar spent).
Marcell was and is a high maintenance guy - I’m not making excuses or letting him off the hook —- just acknowledging it’s a waste to take the stance that the team has no role in the success of these guys
