I haven't seen enough of Kabongo, but I've heard great things so far despite his early struggles. Good leadership, knows how to play the game... and he's Canadian.
I wouldn't mind Kendall Marshall too. In fact, I'd condone Kendall. He won't jump out of the gym but he'll make the smart plays and gets the job done.
Can't go wrong with picking up one of Kabongo, Marshall, or Teague in the mid round.
