In the days leading up to the Boston Celtics' first day of training camp Phil Pressey couldn't sleep. Rookie jitters perhaps? "I'm anxious nervous all that" a grinning Pressey told Before the Celtics' Media Day on Monday Pressey said he watched the Media Day of other teams beforehand "like two or three times. Pressey added "I was amped up. I'm amped up right now. I'm ready to get started." Only time will tell if all that nervous energy will work in his favor as Pressey and the rest of the Celtics officially kick off the 2013-2014 season with Day One of training camp today at Salve Regina University in Newport R.I. Pressey will be one of three rookies with guaranteed contracts (Kelly Olynyk and Vitor Faverani are the others) in camp all of whom are in the hunt to play this season. But for rookies often what's seen in the first few days of camp is a far cry from what they are truly capable of doing on the court. Austin Ainge the C's director of player personnel said there's a process by which most rookies have to learn how to play at this level off their instincts. "Most of the time they have to process so many things that they play a little robotic and make more mistakes as a result" Ainge told However most of the Celtics' rookies have been in town for weeks which bodes well for them finding their way in camp sooner rather than later.
