I'm not sure if this has been brought up before because I've been away for awhile, but when you watch this guy one player comes to mind, Ryan Freel.  They both posses great speed, and they are both gamers.  I've always hated it when Ryan Freel is in Cinci's lineup because he plays with so much passion and guts out every at-bat.  Watching Theriot play really reminds me of Ryan Freel.  I know people have speculated Theriot would be a good utility guy and I really hope he can stick with the big league club and evolve into that reliable scrapper who goes out there and plays the game right.
