When Sanders wasnt doing the spectacular runs he was often caught in the backfield for losses.Ask any football watcher over 50.
Partly do to his diminutive size,running style and a not great offensive line with the Lions.
ps-I like Croom.
pss-Allen turned good protection into an emergency many many times due to his standing there like a wooden indian staring downfield and not moving his feet. Its not ALL the O line's fault.
Rob Johnson did that a lot as well.
