I understand Roy's point - he had certain preferences for this summer and believes that Ainge was wrong not to pursue them.
The thing is that most ppl who accept Ainge's decisions (or lack thereof) don't surrender their judgement to a higher authority.
Personally, I will come back to these summer's decisions, but I think it will make a lot more sense to do so in a couple of years. For the time being, I give Ainge and our FO the benefit of the doubt, but this is a far from having blind faith in everything they do.
