Garza will either end up playing (at the very least being on an NBA bench) for 10 years and then coaching...
Or playing in Europe for 15 years, making a very nice living, coming back in the off season and running camps (making even more money)
The guy is annoying as ****...but to think he won't have a shot to (at the very least) sit on an NBA bench at 7 foot, with the ability to shoot the floor and play hard...well...I don't know what you are thinking.
The keys are his height, hustle and shooting. If he was 6'8, I would agree that he would have no chance. 6'8 guys are a dime a dozen in the NBA.
