depending on the return, and it wouldn't take a ton, but I'd certainly deal him. the guy could make a decent enough spot starter, mopup type guy, but his control and splits won't give you anything special. If you could flop him for a bonifid major leaguer or two, don't hesitate. He's an injury risk for sure, already hitting the 60 day DL in season 12, which probably explains his big jump in ratings from season 13 to the start of season 14, but he won't improve a ton past where he is right now.
Of course if the offer is of nothing useful, or a bench player at best, I'd rather have the extra pitcher that can occasionally spin a gem or give you innings out of a mop up role than a utility player that's going to be a dime a dozen.
