It'll be interesting to see how often he updates his blog. It would be great if he updated at least once or twice until the season starts (or at least until he takes over starting duties.) Of course, I don't always blog that often, so I don't expect him to either. :)
Ricky Williams, RB for the Miami Dolphins, typically stays pretty active on his online journal. I believe he even creates and maintains the site himself (if not, Ricky let me know—I'll help you clean things up a bit—or if you just want help, let me know.) It's pretty interesting when a player wants to stay in touch w/the fans and blogs/online journals are a pretty easy way to do it.
