Lots of little things:
1) great acceleration
2) the 180 spin move he put on in St Louis
3) dropping a mirror on his toe in 1979, missing Roger's last reg season game
4) the phenomenal game he had against the Rams in the 1980 playoffs
5) his early bout of fumblitis
6) his long run for a TD vs Philly in 1977
7) Darrell Green running him down on MNF
etc.
