Max Triplett is one of those guys who can be a serviceable big. He plays inside on the block, gets points and rebounds, defends. But, we already have a couple more of those guys in Fouss and Keba - they have great length and with their leverage and athleticism, they play "bigger than they are."
Remember that this is likely to be an NBA-style offense - it's less about bigs and more about athletes and roles.
