Irving is a 19 year old point guard from Duke. At the NBA Combine he measured 6'4" and weighed in at 191 pounds. One of the main concerns regarding Irving is the fact that a toe injury sidelined him for most of his season at Duke. He managed to play in only 11 games, but was mighty impressive when he did take the court. He averaged 27.5 minutes per game as a freshmen and tallied 17.5 PPG along with 4.3 assists per game.
People don't like this year's draft because there is no surefire superstar a la Blake Griffin or John Wall, however, Irving is going to be a solid pro. He's got all the tools to be a very good point guard in the NBA and reminds many scouts of a young Chris Paul. That's not to say he will ever reach the superstar status of Chris Paul (the best PG in the NBA), but it's a pretty good name to be compared to.
Kyrie Irving allows the Cavaliers to look into moving Ramon Sessions in order to acquire more picks or assets. While Baron Davis showed that he still has the ability to be a competent point guard, Kyrie Irving fits very well in Cleveland. We know that the Cavs are going to be rebuilding for the next couple years and by adding a young, solid point guard, it will make the process much easier. Derrick Williams may fill the holes that the Cavaliers have a little bit better but when you are as starved for talent as the Cavs are, you take the best player available. In this draft, the best player is Kyrie Irving
