My comment wasn't incorrect. Contracts aren't fully guaranteed in the NFL, and that was the context in which the statement was made. I suppose I could have added the word fully in there, though it wouldn't have changed the essence of my point. Even so, 200k guaranteed out of 1.5 M isn't much. Also, there is no guarantee he'd have a contract for next year either. In that context, the statement "contracts aren't guaranteed" also makes sense.
Bottom line, players have the right to attempt to renegotiate their contracts. Teams have the right to terminate contracts at will, saving any unguaranteed money from being paid. In that light, I don't have a problem with Mincey missing a few days if it means he can get an added year to his contract. And maybe a little bit more cash.
