Boston Celtics star Kyrie Irving is confident he’ll be ready for training camp after undergoing season-ending knee surgery in March.Speaking to reporters at USA Basketball minicamp Thursday in Las Vegas, Irving said of his prospects for participating at the start of training camp, “Easily. Easily. Easily. It’s just the summertime. This is probably one of the first summers in my last seven years where I’ve actually had time to kind of develop and work on things that I want to improve on.”Irving is just a spectator at the minicamp as he has yet to play five-on-five full contact yet, he told ESPN. The 26-year-old has been cleared to take part in basketball activities and do one-on-one work, though.
