I think Hansbrough can succeed in the NBA as a PF (don't know why anyone would consider him for SF). He won't be a dominant player, but could prove to be a valuable bench player or marginal starter on a weaker team. I think he will definitely be a value pick in the 2nd half of the first round.
The main reason I think he will be okay at PF is that his measurements were very similar to Griffin's at the Combine. (6'9 and 234 lbs) So his size is fine - just needs to put on 10-15 lbs to avoid getting pushed around by bigger guys.
Also, much smaller guys like Powe and Davis for the Celtics have shown that you can get your shot off as an undersized player if you are smart about how you use your body and the rim (neither guy is more than 6'7).
The one physical area that he falls short in compared to top PF prospects like Griffin is his standing vertical, which according to scouts is probably why he tends to get blocked at the rim at times.
I also read some positive stuff today about his workout in Atlanta. Could be Atlanta trying to push him up in the draft, so someone else falls to them, of course, but here you go:
On 10-point scale, Tyler Hansbrough's Sunday morning workout for the Hawks at Philips Arena ranks at the very top of anything conducted in the past five days. It wasn't any one thing in particular that had the Hawks' coaches buzzing. It was everything. Hansbrough's energy, effort and obviously better-than-advertised shooting and athleticism caught more than a few folks in attendance by surprise. "He kicked the meter up. It was off the Richter Scale," said Hawks assistant coach Larry Drew, who ran the team's workouts all week...
"If this kid is still there at 19, the Hawks better not hesitate," another Eastern Conference executive told me Sunday afternoon. "The kid's a dream for coaches in our league, because he's going to come in and crank things up automatically. He's just wired differently than most of these other guys."
