Having read a ton of about the early Celtics and been a fan since the early 70's Celtics, I gotta say, I have no problem with all the retired numbers. You can't unretire 1 and 2. Walter Brown and Red Auerbach are why the Celtics are here and are great. Ramsay, Sharman, and Sam Jones were transformative players, much like Cousy. Havlicek, Cowens and Jojo were as important to the 70's titles as the Big 3 were to the 80's. The 80's Big 3, Russell and Pierce are no brainers. Reggie you have to as he gave his life for this team and out of respect.
Are yhere some in there I might not have retired, sure. But stars of the 60's that put on the greatest championship streak in all of sports, need to be recognized. Never understood Dennis Johnson or Cedric Maxwell being retired but it is what it is.
We have tons of numbers that can still be used. No sense unretiring numbers. Every number up there has a story and a reason to be there. Let's respect that.
