I'm going to disagree on the latter part. I was at summer league, and the part of his rebounding that impressed me the most, wasn't his out of area rebounds, although I love that part of his game, but the rebounds he got in a crowd. There were numerous times he was surrounded by three or four opposition players and he was the one that came down with the rebound. Now you can argue that it won't be so easy when he comes up against the Kevin Loves and Dwight Howard's of the world, and I would agree. But he has a terrific second leap, and I think he will more than hold his own. His rebounding isn't an aberration, he averaged over 10 boards a game his last two years at Oregon St.
As for position, I don't see him playing any position other than PF. I guess you could throw him out there at the center position if the other team were to go to a small lineup, but I certainly don't want to see him matched up in a man to man situation with Marc Gasol on a regular basis. By the way, since someone mentioned him performing better than Vonleh, I decided to look up how they measured up from the measurements at the combine.
Vonleh: 6'9.5"with shoes, 247 pounds, 7'4.25" wingspan, 9'0"standing reach.
Moreland: 6'10.25"with shoes, 224 pounds, 7'3.5"wingspan, 9'2"standing reach.
Much was made of Vonleh's huge hands, which certainly help when rebounding the ball, and catching the ball. So once again.
Vonleh: 9.75" hand length, 11.75" Hand width.
Moreland: 10.50" hand length, 12" Hand width.
So as you can see, Moreland actually has larger hands than Vonleh, along with being a little taller and longer. Not that any of these stats matter if they don't add up to results. On paper Vonleh looks like the better overall prospect. But it wouldn't be the first time that an undrafted player, or a 2nd round player ended up being better than a lottery pick. That hasn't happened yet in this case, and I would advise against getting overly optimistic. However, just maybe we've discovered a diamond in the rough. Maybe!
