What a tricky situation. On one hand, I don't think the Cavs want to give Love max money because between him, Tristan Thompson, Lebron, and Irving, the cap is going to be pretty maxed out. Especially if Lebron isn't taking any discount like he says he won't. They are also going to have to pay Mozgov in two years. They gave up two first for him so they won't want to just let him go. He also outplayed Bogut in the finals pretty handily.
So if Love does opt out, he might not have the decision of going back. And does he want to go back anyway? Remember when he was a max money making spot shooter? Or when he wasn't playing in the 4th quarter of games?
But, will Cleveland have the space to get another max guy anyway? I think what Cleveland would really want is to sign Love and then trade him for a guy they really need.
