What's he going to do, grab a gun and start shooting people? Seriously, I don't understand why people make this argument. Coco Crisp is a good OF. He can play all 3 positions, can run for speed, has occasional power (if I wasn't lazy I would emphasize occasional) and is a switch hitter.
I think as long as he's under contract he WILL go for it because he won't have a choice. More likely than not it would be almost a reverse Pedroia situation, where they would 'give' Crisp the starting spot and have Ellsbury fill in occasionally a la Cora. Crisp may be confronted with a choice: start on a crappy team and value playing time more than winning, or play on a potentially WS winning team where 4 OFs play regularly but Crisp is the super-sub.
If I had a multi million dollar contract and someone said, "You know, we'd rather you just sit here... but we'll still pay you" I wouldn't complain about it. It isn't like Crisp needs to "prove himself" so some other team will give him a multi-million dollar contract. If he were a FA next year or the year after, even as a bench player, he would get a multi-million dollar contract simply because of the facts I listed above: switch hitting, speedy, versitile OFs are a commodity in this league. He'll be fine. And it's not like he is going to get Carlos Beltran money even if he starts every single game.
I'm still a fan of Crisp as the 4th and possibly moving WMP.
