I still think, even after last year, that Baker is a bit nutso (a lot of kind of odd 'resting' of players, particularly pitchers, despite the rap he got for working them hard...). Personally, he will tell guys they are doing well to try to make them do better and will be inscrutable as far as keeping everyone who IS playing feeling groovy about themselves, even if they might not be-- in fantasy terms anyway. That's why players like him so much but I think that the Cubs are adopting the most conservative strategy for the injury. As a Cub Fan, I totally appreciate the strategy, instead of trashing their investments, but I can see how if I'd succumbed to the temptation to draft Prior I'd be shopping him around too.
They proved last year that it is possible to do well, even w/ a slow start so they will play as well as they can until they are CERTAIN that Prior is better. W/ both Cincy and Pittsburgh coming out of nowhere to rough them up, they may need to rethink that but I see Prior's 'fantasy value' going down the drain at this point. They have zero motivation to share the correct info w/ the legions of fantasy players who are curious.
I have a Prior jersey (brilliant gift from Mrs. AcidRock...) and REALLY like him a lot but, in terms of my $10 fantasy bet, I went w/ Vazquez. It's a long season but jeez, in terms of when he'll play effectively, you have to kind of add a month to get in shape onto however long the ankle or whatever is going to keep him out.
The one thing that he MIGHT be of use for, assuming he comes back sometime over the summer, would be towards the end of a H2H league and the playoffs. When he's on, he will REALLY rack up some numbers for you. W/ a 10 team Yahoo league, you're talking a bunch of teams in the playoffs anyway and, if a monster pops into your lineup, it could take you a LONG way...
