If it is a really nice graphing calculator, I think it would be taking advantage of them to do this. Whoever gets Lidge will need it to calculate the functions for the very long sweeping trajectories that Lidge helps batters to generate.
See...I think he is at his best in tight situations....problem is, right now, he is at his worst period...I think he has a closers mentality (as weak as that mentality may be right now) and will never be able to excel in a middle relief situation. I saw the article where he said he was ticked off at the demotion....gimmie a break Brad...its time to give someone else a shot for cryin out loud.
He's done it before, and I think the whole "my role is X" notion with relief pitchers is totally overblown. Will take some adjustment, sure, but there's no reason he can't pitch in whatever situation. He'll adjust, or he won't be a major leaguer for very long; he's in no position to dictate things, he just needs to do his job.
