I have said it numerous times, I believe Bender at 3rd is the best way to go. Is he a sure thing, of course not.
To simplify.
In today's NBA bigs offensively you are looking for:
a) a roller (DJ, Drummond, Tyson Chandler, AD mold)
or
b) a spacer (Dirk, Kristaps, Frye mold)
On defense, you are looking for:
c) a rim protector (Gobert, Bogut, Ibaka mold)
or
d) ability to switch on PNRs (Draymond, AD, Noel mold)
Bender has the best possibility, potential to check all those boxes of all the prospects in this year's draft.
Even if all of those skills are to be mediocre, he would still be a great piece. That's just too much of a versatility and if some of those skills are above average, he will be a revelation.
