Robin Lopez (I feel like he would've been a great fit with the C's) or Tobias Harris. Both would've been difference makers.
Have to agree with Lopez, solid defensive center and got signed for "small" money, at least by today's standards.. I think he would have been the smarter play over Amir, but time will tell.
Also agree with Tobias, and not fully convinced we couldn't have made a move for him. Orlando had no interest in signing the kid for 10 mill half way through last season, I think a decent package offered to them for a sign and trade would have made him ours.
I personally thought they drafted Hezonja to move on from TH.
