Don't get me wrong, I am happy the FO was able to extend Wood, who I believe,(if he can stay healthy) will be our center for the next decade, and I'm happy about them re-upping Stevie, and even Kyle Williams,(though he seems like he may be on the downside), and yes, paying the big bucks to go after Mario.
However, with that said, I still believe they could've at least re-signed ONE between Levitre and Byrd, if not both. If it in fact is the case that neither wanted to be here, which is a distinct possibility, then God bless them both and don't let the door hit you on the way out, but, as vincec just said, they had plenty of money to re-sign both.
