I am not going to pretend like I have ever seen Celtics draft pick JR Giddens play. However, judging by what people are saying about him and his type of talents he reminds me a little of Tony Allen. (Tony Allen is a free agent and most likely gone) Judging by the youtube clips of Giddens, at the very least he may be in the line of recent great Celtic dunkers like Gerald Green and Kedrick Brown. Lets hope that he has more of an all around game then those 2. Here are some youtube clips of Giddens dunks:
