I wouldn't trade Ramos, either. Flores looks like he needs time in AAA if he's ever going to get back to what he was. Norris is probably a couple of years away and is no sure thing.
If Span can't be had and the Rays are asking too much for Upton, then just stick with Bernie for the rest of the year. We're not winning the division or wild card, anyway.
I don't think the Phils need Upton. They need a corner OF bat. The Braves might decide to upgrade from Schafer and whoever, though. The Indians have Sizemore for 8 mil next year so they probably won't trade for him. The Reds have way too many OFs already even after sending us Gomes plus they have Stubbs right now.
I don't see too much of a market for all these CF's. But if the Rays and Astros and Twins are holding out for too much, just punt and wait for the offseason. That would be a lot less bad than trading too much for one of those guys right now.
