You guys are missing the point. It's not Calderon vs Flynn. It's Calderon and Walker/Knight vs Kanter/Williams and Flynn. And while Walker/Knight *might* be better than Flynn (it's not even a sure thing), I'd take Kanter/Williams for our future over Calderon any day, and I'm a staunch believer in Calderon.
You do realize you usually have to give up something to get something? You can't expect other GMs to bend over and hand you your long-term solutions, ready to go. If a player was a sure thing already, there wouldn't even be a need for conversation.
