I actually agree with you that EJ won't likely be an NBA superstar.
He doesn't have Wade's explosiveness or ability to finish at the
But, he's already a better, purer shooter from deep than Wade
will probably ever be. As a SG, that ability will spread the court
for his teamates. And that spread court (unlike in the NCAA where
teams can double easily w/o consitently paying for it) will also allow
him room to drive it that he doesn't have right now.
Of course, that means he'll need to develop a mid-range, pull-up
game (a big facet if Wade's game) as he adjusts to the NBA. If he
can do that, he'll be a very prolific, offensive player at NBA level.
