There really aren't all that many lazy professional athletes out there. The very fundamental nature of their job usually demands a pretty high level of un-laziness. And shush, I realize "un-laziness" isn't a "real" word, but you know what I'm talking about.
Lazy players are a very small minority of all professional athletes, but obviously they do exist. There are a few special players in every sport who buck the trends and manage to keep their jobs, despite playing without heart, urgency or enthusiasm.
