Yeah I was really surprised Smart was first. I would think Isaiah and Crowder are 1-2 and Smart is third. Olynyk isn't bad and you could argue that right now he's producing more than Smart, but he's also three years older and has less upside. Of course, each team would rank them differently based on their needs.
Now that I think about it Crowder might be #1 because he's on a cheap contract for 4 more years. Thomas only has 2 years left after this one. Crowder also plays a position that isn't as deep as Isaiah's. On most good teams Isaiah would be a sixth man, but I can see Crowder starting for one because he doesn't need the ball in his hands to score. Good teams already have better guys who dominate the ball and they just need rebounding, defense, and spot-up 3s, all of which Crowder excels at.
