I was pretty sure about Cumbie until the news about Anderson dropped. It'll depend on how much the Astros are willing to send his way, but more than likely, he'll be back. Kid will probably be the Friday starter next year and would probably go in the top 3 rounds and there's no way he gets that from the Astros now.
Coldiron, not so sure on. He's an older guy as he's already redshirted and he was out this year due to academic issues. He might just move on and start his pro career.
