Why was Omameh a two-star?

Submitted by CincinnatiWolverine on

When this recruiting class was getting signed, I was following everything on rivals, but I had not discovered Mgoblog yet. So, I am sure this was discussed a couple of years ago, but why was Omameh only rated a two-star(on Rivals) coming out of high school? I know they had him as a defensive end, but that still seems low for a guy that many were predicting would become an offensive lineman. Just curious.
