i dont think stamina could be a factor for salary increase, but free throws has but isnt that as normal skills do.
also i notice of all players, sf is the most dynamic player one should have in terms of skills, he has to have the flexibility to perform at best whether inside and outside in defense or offense.
just as like he could be a awesome penetrator but has a decent jumpshot, of all it also depends on the offense your employing but i think he also has to have rebounds and blocks to go with his defense to really be effective.
its juts me
