The OL didn't help
A RB stuck still behind OL who cant move takes excessive body blows while stationary (no give).
The faster over the LOS the better.
For me (and people like Carl Banks) the pre-draft worry was being too heavily muscled from lifting.
The closer the muscles are to their max limits the more power is combined with proximity to weakness.
Benching 425 and squatting 600 means strong muscles that are also close to their point of failure.
That's even worse if players juiced and their overstrong muscles rip away from lagging tendons
Take a consumer car and drive it to its max speed all the time and you'll need a bunch of mechanics pretty soon.
Stanford reduced injuries over 70% when they went away from heavy max weights
