I wouldn't. Depends on the team. Marble is the superior on-ball player. He's got a better handle, ability to penetrate, play in the pick-n-roll. Stauskas is a superior off-ball player as a catch-n-shoot guy, a cutter, a slasher off close-outs.
As for the NBA, Marble is going to be below average as on-ball player. NBA teams won't let him dominate the ball, because guys like Ginobli, Parker, Diaw, Lebron, and D-Wade dominate the ball in the NBA. Stauskas' advantage is that, as a superior off-ball player, he's better suited to play next to those guys. He doesn't need the ball in his hands to do his thing. Marble, at this point, does.
But as far as college, Marble was pretty darn good on-ball player. We also needed his skillset more than we needed Stauskas' skill set given our roster. Marble and Gessell were the only guys that could even dribble last year.
