I'm watching his Hudle videos, and I see Hargrove as a LB in college. Sure he's 250 already, but he simply is slow off the line. He sheds blockers well, has good pursuit of the ball, and is an absolutely nasty tackler, but he's slow off the snap and pretty much gets through smaller HS linemen by being stronger than them.
@LoadedItalian - Offers from Ivies are a sign of high intelligence, not high character. I could point to thousands of politicians and businessmen, past and present, who went to the Ivies whose character is terrible, and many of them were raised by someone from those same places.
