I am not nearly as down on Love as some have been. He IS making an effort on D as far as I can tell, and he contributes with some nice passing (the full court feeds as well as nice entry passes to Mozgov).
However, his shot is clearly off, and it sure looks like the back is involved. I'd have to imagine that Kevin and the team are just trying to get to the All-star break to give it some rest. Having seen what the rest period did for LBJ, I'm trying to be optimistic about what it can do for Love.
At some point, I think Blatt is going to have to utilize smaller lineups with Marion and LBJ manning the 4 to enable Love to get some games off. I realize that he may be unwilling at this point with the team just picking up momentum.
