Hopefully not: Ray, KG and the Captain should retire as Celtics when Rondo & the New Power Generation (Bradley, JJJ, Green...) are ready to carry the team themselves.
That's two more years, IMO, of the Big Old Three mentoring the young kids and playing less minutes on lesser roles. That's how Red built the Celtic tradition, and that's how it should be. I know there wasn't the salary cap or free agency, but how many teams have their legends coming to practice or watching from the stands? The Celtics.
7-8 mil/year for KG and 5-6 mil/year for Ray with no-trade clauses and partially guaranteed second year would work for both parts. KG becomes assistant coach in the Clifford Ray mold. Total win.
