The term "superstar" gets thrown around an awful lot, but let me tell you, I know a real superstar when I see one.
When I entered my first NFL training camp with the Tampa Bay Buccaneers, I met Warren Sapp. My first thought was that he didn't look all that impressive, and I wondered what the hype was about.
Then we put pads on.
I'll say this. If the coaching staff didn't tell Sapp to take it easy in practice, we wouldn't have been able to practice. The guy was a force of nature on the football field, and he'd wreck whomever he was going up against.
