Mozgov is good, but was not worth two 1st round picks for a rebuilding team like us. He's totally worth it for the Cavs because they desperately needed a healthy big man for the playoffs, as this run has proven, and because their picks will not be very good. They could not afford to wait until this summer for better big men in free agency also, because they don't have the cap room for them, and because they would have wasted an opportunity for a championship this year.
We however, can get better big men this summer from free agency, or from using our assets to trade up and draft one. Why waste two 1st rounders to get a so-so big man before this summer? It's not like we were going to contend if we had gotten him. Save those assets for better use.
