I'd rather move Reyes myself. He'd probably get more in a trade, and his injury history really scares me. Hopefully Walt will make some sort of move, but I don't think they're desperate....yet. Everyone *should* be healthy by the first part of September, and the division isn't going to make up 10+ games with the pitching going like it is, so while it looks pretty bad right now, I don't think a move is absolutely necessary. I imagine there will be plenty of moves during the offseason to get younger in the OF, but there's really no pressing need right now, unless there's a lot more wrong with Walker/Sanders/Rolen/Edmonds/Pujols/Yadi than they're letting on.
Hopefully freeing up some roster space to give these other guys a chance will prove to be a good thing since they'll probably be needed in at least a limited capacity during the playoffs.
