Cordy is a nice chess piece to have. We did well enough without him, so the pressure is not there to keep him. When healthy, he's a solid LT, but we showed we can do just fine without him. The real question is how much value other teams place on a solid LT with health issues.
Personally, I think we'd be lucky to get a 3rd rounder for him. Still, that gives McBeane the opportunity to include him as part of a trade-up scenario and still retain a decent set of draft picks.
