I really agree that Utah need some fire, some passion and anger brought to the team. Everybody seems so laid back on the roster as is. Smart stands out in this aspect, the talent is there, but so is the fire. I personally like the fact that he got caught up in a few incidents during last season, shows his fire, I love players like that. Randle is another one who probably fits here too, I haven't seen as much edge to him but I've heard he's a man out there. I saw a few games and like his physicalness.
I never watched a full game of Vonleh, only relied on highlights and draft chatter. Can't comment too much on him but from what I've heard he is raw but will turn into a very good player.
My pick if we stay at #5, Smart (although his flopping annoyed me in some games, he better quit that). Otherwise Randle. I'm still annoyed that our hopes of landing Jabari are almost gone.
Edit: completely forgot about Aaron Gordon, if he has some hunger and fire in him, I would be happy with the choice. Really like tough defenders/rebounders, not sure how good he can be though
