I know the general rule is to ignore the rankings. But there's something a little off here.
He's been a 3 year starter for an unbeaten nationally ranked team, and he's made 81, 96 and 105 total tackles with 3 sacks each year.
In other words, he's not an under the radar kid playing in the sticks, who nobody has ever heard of. He's a known commodity with multiple set of eyes on him and that team each week.
Yet despite all the attention and the tackles, he's still a consensus lower tier 3* (78 on ESPN and 5.5 on Rivals). Its fairly safe to say the recruiting services just don't like him. Even guys who don't camp at all are ranked higher.
I'm not arguing for or against him. But the fact that he's still ranked where he is tells me he isn't getting much of a bump. Definitely not by all 4 sites. Which.. again doesn't matter. But don't expect him jump up at this point.
