Should be a good match up but I think my post play is what changes this series. Horford and KG can't contain the trio of Sanders, Lopez, and Randolph, especially Lopez and ZBo on the offense. Obviously KG is a stellar defender but he won't be able to body up against either of those two when they are in the game.
Lawson isnt as good as Irving and Rubio shouldnt have a problem staying with him on defense or getting around him on offense.
Allen is a tough match up for Martin but Martin has 3 inches on Allen and again will just be able to shoot over him without problem.
Green vs Wallace should be a good match up but I give Green the slight edge on both sides of the court.
I also think people are forgetting Derrick Williams talents off the bench as the 7th or 8th man (behind ZBo then possibly Hinrich.)
I think there is too much versatility for me in the post. I can throw ZBo, Lopez, Sanders, Williams, and Green in the post and keep the fresh legs coming without enough Cavs players to guard them, especially with an old winded KG being battered and bruised constantly in the paint.
