You talking about Charlie strong?Strong and Addae resume don't hold a candle to Mirabal my guy. Neither have turned walk ons into all conference players.
Oline is a position that doesn't need so much raw athleticism as there are lil sneaky tricks and techniques you can use to cover your deficiencies that you absolutely can not use at backer or DB because of the space you have to play in.
Those are the types of things Mirabal teaches.
