Front Number Size & Position

The 2017 Cavs Home/Away jerseys have felt weird whenever I passed by them in the selection menu, and I'm pretty sure that it's because of the Cavaliers front number being too small. Can somebody give me some pointers on how to move the front number a little higher, and on how to change its size? Thanks in advance

Edit* Position info would be really helpful, I'm trying to make the 2008 All Star Game Jerseys.
