if you assume we're pulling the plug on this season and using the rest of it as development time, getting someone to play 1B (trying out some young guys we have, moving Wood there in the offseason, an acquisition of some sort) next year to replace Luis should be doable, and this is as high as we were going to be able to sell on him. it's not like he was going to be around past next year unless he severely regressed.
I think we've seen the difference 2 really good relievers could make.
