you have to offset it with one 100 lbs. player. This would reduce a lot of injuries

Until the 100 pound guy (ridiculous) is literally killed by the 350 pounder.

[alternatives?]

I would guess three players at 200 pounds each would be more effective than one 350 pound player and two 125 pound players. I doubt if a 350 pound player has the speed to catch anybody in this scenario.
