Football and Desire

The news on JaMarcus:

According to a league source with knowledge of the situation in Oakland, the hefty quarterback has beefed up to 300 pounds. 

We're also told that the former LSU star isn't getting good advice from his family. 

"It's a drag on the kid and they encourage his poor lifestyle," an NFL source told National Football Post.

My sense is that there are people who are often talented at a specific thing, but don't actually enjoy it that much. Moreover, my sense is that pro football requires a certain amount of base level athleticism. Then after that a bunch of other factors determine your success, a desire to play among them. To be sure, when you watch, say,  Gale Sayers athleticism is still extremely important. It just isn't enough.
