I have been a huge ND fan for the past couple of years and feel that I can give a somewhat intelligent analysis on him having watched nearly every televised game of the Irish. Harangody's positives are that he has surprising athleticism, always seems to get his, good work ethic, runs the floor well, and continually improves the aspects of his game that will make him an NBA contributor (fadeway jumper, running hook, distance shooting, etc.) However, he is not without his downsides as a player. He forces the issue way too much, hasn't improved his passing in each of his three years, he is undersized, his stats are somewhat inflated (he took most of the shots for the ND offense and nobody else on the team rebounded so he coralled the majority of NDs rebounds), and he did not perform well against NBA caliber competition.
I'd be interested to watch him during camps and in all likelihood he'll be back in South Bend next year. However, should he come out, I would not necessearily want the Celtics to draft him. He would need a few years in the NBA to establish a role and to find a consistent niche he can bring night in night out. I don't see him bringing that to the Celtics in 2009-2010. Thus his value to them would be greatly diminished.
