Let's start with each player on your batters side:
C-Paul Lo Duca is getting weaker as getting older and is not going to be able to deliver as much this year and in the coming years. He is not even close to the top of the "Catchers" list, but really all catchers do suck, so you don't have much to worry about at all.
1B- Albert Pujols as you may or may not know is the #1 player in the MLB. He is going to give 50+ home runs and 120+ RBI's. This guy is a heck of a power hitter for that sake and does clutch at times.
2B- Chone Figgins like you said is on the DL so you have Placido Polanco. Well keep checking until you can put Chone Figgins back in because I don't favor Placido Polanco. He is never safe to go with as a primary 2B.
SS- You're probably thinking "what a bummer!" right when you heard Rafael Furcal was on the DL? He produces good numbers and speed so that's a bad thing he is on the DL. But I think that David Eckstein will do just fine until his replacement.
3B- Chipper Jones is a great average player. He hits an average number of homers, an average number of RBI's, has an average Batting average and steals an average number of bases every year. This player is a great player at every average stat.
OF- Jason Bay is one of the best OF out there and that is great that you have him. He is going to deliever lots of power homers this year and he is just going to be an excellent and amazing player. I have hope that this guy will excel this year.
OF- Magglio Ordonez is not close to being a top outfielder. In my opinion, he'd serve as a back-up maybe 4th or 5th outfielder, but certainly not a primary.
OF- Good pick in Garrett Anderson. He's an all-around well player who is going to do just average this year. (read what I wrote for Chipper Jones; the same applies)
UTIL- Jason Giambi is a strong utility man because he can hit lots of homers and RBI's and is a great power hitter who delivers. This is a great pick and a wonderful spot for him.
BN- I have no comment on Dave Roberts.
So your batting side looks great and I'd rate it a 7/10. You've got speed, power, good average, RBI's, home runs, and OBP.
Now your pitching side is the weaker side. But don't worry about that. Since you have an amazing offense, that will cover you and carry you when your pitching is maybe declining.
SP- Roy Oswalt is one of my favorite pitchers and he is one of the best pitchers in the game. He'll get you wins, ERA, and K's, but the only problem is he might suck this year because Houston lost all of its good offense and without great offense, a pitcher can't win a game by himself.
SP- Jason Schmidt is an above average player who will get you a good number of K's and will put up an okay ERA. (a little shaky and risky though)
SP- No comment on Tim Hudson and Scott Olsen
SP- John Maine is going to be a great pitcher this year. He is going to excel and I can see that. I have hope that this guy is going to be a great pitcher this year putting up amazing numbers.
SP- No comment on AJ Burnett
RP- Nice pick in Trevor Hoffman. This guy is a future Hall of Famer and he is one of my favorite relievers. This guy can get you a good ERA and tons and tons of saves so great pick in him.
RP- Little shaky and risky on Takahi Saito, but I hope it works out for you.
RP- Jose Valverde is off to a great start. He is going to give you a lot of saves, a good ERA, and a couple of wins too, unlike some relievers. Nice pick.
The pitching side I would rate a 6. But like I said don't worry your offense takes care of that.
Plus, this is pretty much a great well-rounded up team so I think you have a chance at your league's winner title. Thank you for taking the time and consideration to listen to what I had to say and I rate this team a 6.5 overall. Good luck!!!
