Disheartening?! Sorry but get over it! I am happy for Isaiah. Good for him! He was the 60th pick of the draft and now he's an all-star...awesome! I am happy for Isaiah and that will be a nice reunion when he and Boogie meet all-star weekend.
I was pissed off as much as anyone when Pete let Isaiah walk but we have Rondo and Collision and that's better duo than anything Isaiah would have offered in comparable minutes.
Let's not be naive. There was not amazing synergy between Boogie-Isaiah like there is between Boogie-Rondo.....so while we did not maximize value for Isaiah as a RFA and he certainly could have a role on this team, his loss is not going to prevent us from being the type of team we want to be.
The Celts can kind of mask his defensive deficiencies because they have a bunch of solid defenders in Smart and Crowder and etc whereas if he was with us our bad defense would only be that much worse.
Isaiah tries on defense but he's only 5'8" and that makes near impossible to challenge perimeter shooters. Given the current make-up of our team I don't regret his loss as much since perimeter defense is our biggest weakness.
