I want the Celtics to sign a young SG (or SF) too, regardless or Ray's return or not. This team desperately needs youth and especially youth which would allow Paul and Ray to rest during the season, by carrying the offensive load.
I would be thrilled to get a guy like Redick for the MLE but only as a backup for Ray/Pierce. If Redick is the replacement for Ray... we're in trouble. He is a perfect bench player but not so much as a starter in the sense that we wouldn't have anybody to play behind him, and Redick gives you minutes in limited time only (20-25 minutes per game I think).
