How many of our 3 star recruits have been bumped to 4 stars?

Their senior seasons have yet to be played. I went back and looked at Griffins film, (you know the guy everyone said was a pawn) and it's decent film if everyone would take the time to check it out they may have a different opinion about the guy. He plays with great leverage, is smart, uses his moves, and is always in the gap he should be to make the play. The only negetive I can find is his size. If he has a good season and happens to grow he would likely be highly recruited. I'll bet he has a great senior season and rises some. Gotta be patient because I believe our coaches know what they are doing.
