Naz has the superior handle, drive to the hoop ability, finish ability, 3P shooting, and is better on the break.Thomas has a good pump fake, in theory, and midrange game.
Imo Thomas seems to be a better rebounder and is a much better passer.
I think Thomas actually is a better ball handler as well. Naz is quicker with the ball, however.
All in all tho, Naz shoots better in games and is less of a liability on D.
