Ok let me just recap why people don't want love
1. His defense isn't elite
Well if you believe in defensive rating he would have been the best defender on the Celtics last year with his league average 104. Maybe he isn't perfect on defense, but Pierce and Allen were both known as poor defenders before they got here, maybe the same thing happens for Love. The last part of a defensive possession is securing the defensive rebound, in that way he should help prevent second chance shots. It's not like Love played against great defenders either. Corey Brewer is a good on the ball defender but his help defense went out the window when he realized he could score by leaking out early to have Love throw him outlets, Pekovic doesn't protect the rim at all, Rubio gambles for steals and Kevin Martin is rail thin. Add Rondo, Bradley and potentially Asik around Love and I would be shocked if Love's defense didn't look better.
2. Trading for Love is going to cost too much, we should just keep what we have
I am huge fans of both Olynyk and Sully (I expect we have to deal one but not both) but Love is 25 years old and already a top 15 player. Do you want to wait until our two guys plus picks develop to support a legit playoff team? I'm not willing to continue to pay money for games if they are just going to throw out the same young squad and I'm not alone. If we keep what we have who is to say Rondo doesn't get tired of rebuilding and in the time it took for our youngsters to develop he left the team? The package for Love brings in Love, but it also increases the likelihood Rondo stays and also the likelihood other free agents come to Boston. In business terms we are paying a premium for the synergy Love would bring to the Celtics.
3. Love gets paid too much
The market dictates what he is worth. I promise you if he hit free agency every team with cap space would be lining up to give him the max. There are probably less than 10 players in the league more deserving of a max contract and many more that get paid the same but aren't nearly as deserving as Love.
