Nice team! Maybe I should miss my drafts more often...
Anyway, Johnson has a sprained thumb and may or may not be ready by opening day. This is one of those injuries that are hard to judge; I was looking for him to bounce back from last year's weak numbers, but now I'm not so sure.
The crop of rookie or sleeper catchers is pretty thin this year. I assume Hall and Fick will have been taken in your league (if not, get one of them). I personally think Ben Petrick is a good risk for 2002, but any owners picking him should have a backup plan. Lieberthal or Varitek might still be available - both missed significant time last year and fell off a lot of owners' radar screens. I'm not quite convinced that Varitek is ready yet, though. A couple other guys you might try are Hernandez, LaRue and Ben Davis, if they're still available.
If you really want a top catcher, however, you'll probably have to try and trade for one, perhaps offering a closer or a package such as Johnson + Erstad. That's probably the route I'd try.
Anyway, your team looks great. How many teams are in the league? Roto scoring? The only thing I'd change would be to add another starting pitcher, preferably to fill a slot left open after trading for a catcher.
