team in the NBA has one (usually two) guards bigger than 6’4”. You can put SAME in caps if you want, but it doesn’t change anything.
The Jazz’ starting guard line is 6’3” and 6’4”. That’s bigger than 6 teams. Which means it’s smaller than 23. That means “undersized.”
Even though guys like Steph/Ant/Donovan are elite, they’re still undersized. They definitely make up for it. But they’re still undersized.
The only way the Jazz age changes the fact that they are undersized is if you’re expecting a growth spurt. Which, reading your posts, you might be.
