His skill set sounds very much like prototypical NT.
Wide as a Coke machine and just as difficult to move, Paea (pronounced pie-uh) has developed into one of the nation's best run-stuffers. His development is staggering in the sense that he signed with Oregon State having only played three years of organized football. ... Paea is a bit of a one-trick pony. He isn't agile enough to put consistent pressure on the quarterback at the NFL level.
His ability to tie up blocks in the middle will lead teams to look at him closely over the first 50 picks of the 2011 draft no matter what scheme they utilize.
...
Run defense: Is quick enough to surprise his opponent with a burst through the gap, but will
make his NFL millions due to the fact that he is a natural run plugger due to his short, squatty build and rare upper- and lower-body strength. Can be knocked off the ball when double-teamed, but flashes the ability to split them and is
rarely pushed far before he's able to plant his legs in the ground and create a pile. Doesn't have the lateral agility and balance to beat runners to the sideline, but hustles in pursuit.
Tackling:
Stays squared and low to knock down the ballcarrier near the line of scrimmage. Flashes explosive hitting ability, with a proven ability to knock the ball free. Tied the OSU record with four forced fumbles in 2009.
Good upper-body strength to drag down ballcarriers as they attempt to go past him. Doesn't have the speed or change of direction to offer much in pursuit.

No. He is not 350 pounds of load, but he is a 300 pounder and, from the description of his body type, I bet he could easily add another 20 -30 pounds.
