AWESOME!!!
The other thing is: Let's say we lose Levitre. Assuming we don't sign a big money FA this year, it stands to reason that the Bills would get a 3rd or 4th Compensatory selection next year. So maybe Buddy is thinking he's trading Levitre for Warmack, a 3rd and $6M in Cap space. When you think about it like that, to me, it makes his departure more plausible and acceptable.
But, that being said, I'd rather keep him.
