It'd be great for Cavs to land a big player, but they will have to get rid of Love, which honestly probably puts them back in the same spot they're at now. Only way I see a Love trade worth is it were for Paul George or Gordon Hayward. Then they'd have to get a big man, and I'm talking a "BIG" man. Mosgov (sp?) was huge for us last year since he was able to grab the boards.
If I'm being honest, if they went and tried to get Dwight Howard that'd be something I'd be very intrigued for. I know he's a fucker and a POS, but he's a beast down low. LBJ would get him right.
edit: I also really like the idea of Melo, DWade, and CP3 come to Cleveland. It'd still be Kyrie at the point, but maybe transition into something crazy like Kyrie/CP3 on the court. More I think about it it just doesn't fit.
