I recall someone asking Marshall Faulk when he was with the Rams if he was "100%"

His response was something to the effect: "No. The last time I was 100% was September 1994, just before I played my first NFL game against Houston".

In other words, once you play a single game in the NFL you are never 100% again.

The Rams have been very fortunate after 2 games and no preseason/OTAs etc.
