There should be weight limits. Left tackle? No limit. Offensive Linemen? 275 lbs. Defensive line 250 lbs.
Linebackers? 225 lbs.
Tight ends/wide receivers 225 lbs.
Lawrence Taylor, Travis Kelce, etc are way too strong therefore they will be disqualified according to my rules.
My nephew, at 6’4’ 275 was considered too light to play center in college. He was a muscular 275 not a blob.
