Dont trade the best C in fantasy. That would be bad.
Dont trade Beckett - again, that would be bad.
I dont think you need to do much of anything with your SP - except to drop Ishii. Seriously, Ishii will hurt your team more than help it - a 1.5+ WHIP??? OUCH!
I would try and trade Glaus - his BA is just too much to deal with at the stacked 3b position. - I honestly would rather have Ensberg there - just to give you an example.
Klesko, Loretta, and Glause all need to be upgraded.
take a look at my squad and give some suggestions if you have the time.
