Yes, Ainge, sell high ................... and blow a title opporunity. That group was supposed to be about a short window to win a couple of titles after the acquisition of Allen and KG in 2007. Sooooooooooooo, that window was still open in 2011, so you go for it.
All the talk about Perkins' decline after leaving Boston is misleading. Of course, he wasn't a great player in OKC. But he was a very good player on that Celtics team because his skills fit perfectly into what they needed. Ainge was so anxious to go quick & small that he jumped the gun and gave up our one advantage over the rest of the league - defense & interior toughness. Replacing Perk with soft Jeff Green just made us another team playing the same style as the others. We lost the edge we had over Miami at that point.
Plus, as you can see from this video, these guys had a special bond that also gave them an advantage. Laugh all you want at the notion, but how do you think Russell and his guys won in '68 & '69 - Guts & Pride Baby !!
