If the end of Moose's regular season and the 04 post season are any indication, he's MONEY.
In fact, I'm not so sure he's that much of a sleeper. Most competetive leagues will see him snatched up fairly early, I'd imagine.
I'll say this much. Yanks fans better HOPE he comes up huge next season, seeing as most of the starters they're targeting seem to be signing with other clubs.
