Your offense is decent. I wouldn't say good.
Helton needs to prove himself again and so does Tejada. Your OF aren't too steady. Jenkins isn't too special and I have no idea which Green you have. Shawn Green? Both Kent and Gary's numbers either stay idle, which would be a great boost for you, or go dramatically down. Rolen is a big question mark, but I think he will rebound nicely. Not '04 numbers, but still nicely.
Sheets is always solid, and might get a couple of extra wins now that he has some offense.
Mulder is overrated, but he'll be decent as well. Buerhle will be good but I think he's overrated. No clue why you have Morris and Byrd. Your Closers are also shaky. MacDougal could be a potnetial 35 save guy. Foulke says he's good now, but there are a lot of negative reports out of training camp. Benetiz should be solid but again, injury situation. Hoffmen will be a solid 35-40 save guy.
Not a great team, but probably top 33% of your league.
