Even with Udoka signing, I still like the idea of keeping Barry. He brings things to this team on the court and locker room that wins games. We won the le for obvious reason: defense, Manu/TP, TD, Pop... But one reason that gets overlooked was being the #1 3 point shooting team (or pretty close to #1, I forget if we got passed up).
When you have bad shooting nights overall, being able to hit a nice %age of your 3's makes up for that. Giving up offensive rebounds some nights to certain teams? You win the game behind the arc and you make that up. Have a problem with turnovers some nights? The 3 ball cleans that up for you. It erases a lot of problems you might have on some nights. Not to mention allows our Manu and TP to drive at will and gives TD some extra room down low.
Barry is a big part of that success. He also is a great teamate in the locker room, on the bench, on the court (always looking to get guys shots). And now with a couple of les, he knows how to stick a dagger in a team for the big wins in June. I wouldn't trade him just for the sake of trading him.
