Fans were ready to give DJ the starting job because fans are suckers for what is NEW and HYPED. When the league figured DJ out and he couldn't counter because of his severe physical limitations, we got a taste of reality. DJ's only hope is to play on a run-and-gun team or to play next to a PG with SG size. Maybe that will happen here someday.
And besides, DJ can partially thank playing next to Felton for his solid rookie year. Left on his own to be PG for a Larry Brown offense, he struggled.
