He isn't even on the same planet as Steph Curry, and I would argue he isn't anywhere near Jimmer Fredette who is bigger and more athletic and still can't make it in the NBA.
Forte is one of those guys that every college team in America wishes they had. He is a very good college player, someone who fans will remember for a long time, etc. But he isn't a pro.
He is in the same mold as Jake Sullivan from ISU, Clarence Gilbert from Missouri, Cory Higgins from Colorado, Jarius Jackson from Texas Tech, Hollis Price from Oklahoma, Byron Eaton at OSU, Jeff Boschee from Kansas, etc.... Guys that stick around for what seems like forever, have some huge games, score a bunch of points, become a fan favorite, etc but are not pro players.
