Well Estrada and Casey have been over exceeding their expectations, so when they come back down it might hurt you... you might want to look to trad them when their value is high.......
2nd and SS are weak........OF is pretty solid but mags is out for a while, not an awful replacement with grissom though, but you could have better.
Bagwell is underexceeding this year, and im not sure that hes gonna break out of it... he prob will, but personally i dont know. Your starting staff is pretty good.... but TRADE LOWE!! he sucks now... hes jsut plan awful!!
Your also pretty weak at the Closer spot too, as you need around 3-4 guys to close for the year unless the two you ahve are foulke and gange... or somthing like that.
Im sorry to say htat this does look like a 9th play team to me, as that you only solid OF guys are Puljos, Rolen, and prob Matsui. What your strength is. is your starting staff.... i would Keep Hudson, wolf, and milwood, and possibly Buehrle..... and trade the others along with Bagwell, Jimenez(if you can) and valentin(if you can) and Grissom....... and maybe estrada and casey if you want to sell high. Youve got solid traid bait to improve your team. Could you post some FAs or WW guys too, so i can get an idea of who's out there.... especailly at SS and 2B
