Yup. He is currently the odd man out, although he is slated to start on opening day (against a lefty). I believe he will end up with a fair number of PAs, maybe around 450. With all the inevitable injuries and his incredible ability to play all positions, he will be a good super utility guy. He has actually been taking time at center field during ST, so he could be Yahoo/SL eligible at 3B, SS, 2B, and OF.
Still, the problem with those type of guys is that playing time is so hard to predict. Frankly, that's good for teh Brewers and bad for fantasy guys. If you want to sit and watch lineups he would be okay, but I would suggest someone else.
Here is a decent thread about Bill Hall.
Of those MI options, I have them projected at (with BP's breakout in parens), in no particular order:
Carlos Guillen - 300/70/12/65/5 (7%)
JJ Hardy - 260/55/12/60/0 (38%)
Russ Adams - 275/70/7/60/10 (16%)
Grudzielanek - 290/55/5/45/5 (7%)
Juan Uribe - 270/65/15/65/5 (26)
Aurilia - 265/55/11/60/0 (22%)
Ray Durham - 270/70/12/55/7 (10%)
Luis Gonzalez - 290/50/10/44/3 (Wow. Just realized he is not in there. hmmm..)
The saest choice there is Guillen. But if you are looking for potential upside, I would go Hardy or Uribe, with a lean towards Juan. Screw that, I'm a homer, go for JJ as he has better power potential.
Hope that helps.
PS. What happened to your Testicles? (Sorry, couldn't resist...) Why did you shorten it to AT?
