Loe was a monster in MVP '05, which is clearly the best indicator of future performance.
Also, am I the only one who always pictures Nic Cage's character from Con Air when anyone talks about him? "Put the bunny back in the box!"
Anyways... he's another on that list of gigantic hard-tossers to watch out for along with Dan Cabrera and Chris Young. And you are right that he didn't get as much attention as either one of these guys, most likely due to the park he's in.
