"The spring is going well, I've been improving a lot," Upshaw said. "I just have to get back into my body and play how I play.
"I've been working on everything. Shooting turnarounds, going off of my left shoulder to my right because I use my left hand more than I use my right, so I got to get better with the right hand."
Even though he has not suited up for a high school team in over a year, schools all across the country are working hard to get a verbal commitment from the 6-foot-11, 240-pound prospect.
"Recruiting is going very well," Upshaw said. "There's a very large pool of schools recruiting me right now. I have the Pac-10, the ACC, the SEC, the Big-10, and the Big-12, the Big East all recruiting me."
With schools from every corner of the U.S after him, the 8th ranked center in the class of 2012 is not quite ready to put one school above the other just yet.
"Not really any schools are sticking out because my recruiting pool is wide open," Upshaw said. "I'm taking in as many offers as I can get right now, so I can narrow it down in the future."
One factor working against Upshaw in his recruitment was his inability to keep tabs on any of the schools that are currently recruiting him.
"I didn't really watch any college basketball this year," Upshaw said. "With me not playing and just being with my high school team, it prevented me from doing a lot of things."
Arizona continues to actively recruit Upshaw, as head coach Sean Miller and associate head coach James Whitford continue to work to build a rapport with the California big man.
"Coach Miller I talk to him, and Coach Whitford I've talked to him," Upshaw said. We have a nice relationship. They're a good school with a national championship and a lot of players in the NBA. It's a good school."
With no favorites at this time, it's no surprise that Upshaw is still trying to put all of the pieces together so he can begin to work towards a decision.
"I don't have any visits planned right now," Upshaw said. "I'll probably decide that at the end of this year. I'll make my decision next year in the spring. I'll be looking at everything, what best suits me academically, basketball wise, and as an environment."
