Murray= My choice when just thinking about numbers.
Bender= My choice when thinking team fit and need.
I think both could be better athletes but with just a little improvement they will be OK in the NBA.
The thing I also think about Murray is the other guys like him in the draft that you can get late like Beasley, Hart, Brogdon and about 2 other guys. Bender doesn't have any one as comparable imo the gap is large.
Labissiere and Poeltl.
Poetly is a 7 footer who runs the floor very well, rebounds well, defends the paint, and has the lateral mobility to step out onto wings. The only thing Bender has that he doesn't is three point range - but Poeltl's jumper is improving, and he's better than Bender in almost all the important big man areas (rebounding, shotblocking, inside scoring, etc).
Labissiere is (like Bender) a very high risk player, but I think his upside is even higher then Bender's is thanks to his more impressive athleticism, smoother jump shot, better inside game and superior rebounding / shotblocking ability. Labissiere hasn't shown much in college this year, and yet he has STILL shown more then Bender has.
