Freshman forward Aaron Gordon and junior guard Nick Johnson will leave the Arizona Wildcats early for the NBA, the players confirmed at a news conference today at McKale Center.

However, freshman forward Rondae Hollis-Jefferson and sophomore center Kaleb Tarczewski will return after considering a departure, UA coach Sean Miller said.

"I wholeheartedly support Nick for being here three years and Aaron for being here for one," Miller said. "The only thing I will tell you is it's bittersweet because these two guys -- people like them don't come along very often."

Gordon said the thought of returning to UA and having a chance to win a national championship was "huge," but decided to make a decision based on his professional future.

"Arizona is going to be successful with or without me," Gordon said. "That's just the nature of the program."

Miller said both players went through an extensive decision-making process with their families, and received an official report from the NBA's advisory committee last Friday.

Gordon is projected as a lottery pick in the June NBA draft. Draft Express has Gordon as the No. 8 overall pick in its 2014 mock draft, a slot that would earn him about $5 million guaranteed over his first two seasons under the NBA's rookie salary scale.

Meanwhile, Johnson is projected as a second-round pick who might elevate himself into the first round. Miller said during last season that leaving to become a second-round pick would be a significant setback but said today that Johnson received enough positive feedback to suggest that leaving is a good decision.

"Generally if someone leaves early you want them to be a first-round pick," Miller said. "Learning a lot form the feedback we got on Nick, looking at how physically developed he is... there's a chance he comes back for that fourth year and maybe not be as coveted.

"Nick knows (his prospects). He is not in La-La land."
