I wasn't disagreeing (I too would keep Fitz). I was just pointing out your somewhat refutable prognostication.
The best way I can discribe my advice would be that if you hold out until the draft unfolds, Fitz's value is going to remain the same. Slaton, however, could see a decrease in value. Worst-case-scenario, offer him this trade after the Houston landscape shapes itself out. I don't think this is a bad trade, persay, but why not use the luxury of finding out what's going on with Slaton if you can afford to do so?
