don't panic whatever you do. its a good team and will do fine. some minor tweaks and you'll be even better.
start peralta over tejada. If you have a utility, thats where i'd put prince. otherwise i'd trade him, preferably for an ace starter or a good starter and ace reliever combo. outfield isn't going to wow someone but its solid and will produce.
you have three good pitchers in slowey, danks, peavy. Lee, i'm not too sold on. myers is meh IMHO. unless you have strict IP limits, i'd look to add someone else to bottom out the rotation.
Ray isn't closing and seems rusty - control is a big issue with post-TJS pitchers, so he's not guaranteed the job as long as sherril plays well. you need another closer, though. LIdge can't carry you.
