Losing Ray is tough. He is a hall of famer, yadda yadda yadda. But this team is pretty deep on the perimeter. They have Rondo, Pierce, Bradley, Terry, and Green. As long as everyone is healthy, that is a very strong rotation on the perimeter. Throw in maybe another perimeter defender/shooter like Pietrus, and your set.
But, what this team is missing is reliable, rotation quality big men. But they have one who they retain Bird rights for in Krstic. He is not perfect, but he brings a level of skill this team can use, and when combined with KG, Bass, and Sullinger, and potentially someone like Wilcox or Stiemer, he can be really healthy.
The problem was, if they signed Ray, it might have been tight to sign Krstic below the hard cap "apron" of $74 million. Now, they have plenty of breathing room. I hope they use it, and bring back the big guy. Solidify the front line a bit more, and look at the bright side of Ray moving on.
