If you have DL who are strong enough at the point of attack and quick enough to disrupt you have to double team him. The more play makers the more offense starts thinking and having to adjust . They are then playing on their heels. A 300 lb DE is a big DE . Spears and Cody are Both around 300 lbs . They both seem athletic . My thought would be a tall DE ( 6 ft 6 in - 6 ft 7 in )about 320 lbs would be perfect .
