The times he has played 1st grade I don't think he looked out of place, he's only had 11 first grade games of which 8 were winning games, has a tackle percentage of 93% , 2 of the 3 games lost when he played he came on as a 18th man, the other game we lost of the 3 he played 80minutes in the 2nd row against the Storm which we lost 24-22 due to Nathan missing 2 goals and going off injured, Mav as a rookie got through 36 tackles with 2 misses that night, I personally think he has a LOT to offer in 1st grade
