Lieberthal is a solid offensive catcher. Huff is fairly weak offensively for a first baseman and is also kind of risky. You generally want a guaranteed .300 hitter with 100 RBIs at the 1B position. Biggio should give you about average performance at 2B. Vizquel is a little weak for a starting fantasy shortstop, unless this is a 15+ team league. If you get Hinske, you will have a solid third baseman. You have three strong outfielders but I would be a little worried about having all three starting outfielders from the same team. That could make you more prone to streakiness or running into good opposing pitching, especially in a head to head league.
Your bench is good but I would recommend starting Olerud and not Huff at 1B, since he is far safer and more consistent. I think Kearns will have a breakout year this year. You have two great pitchers in Pedro and Mulder, and the best closer in baseball. Beyond these three, your pitching looks fairly weak although Kim may have a breakout year as a starter, he is still not proven. I would recommend trying to trade Vernon Wells for an upgrade at one of your offensive positions and picking up a sleeper closer, such as MacDougal off waivers.
