Wilson will come down to earth soon, Helton is injured and is not likely to come close to last year stats but shoudl still be a good 1B, loretta is mediocre at best at 2B. 3b/SS/OF are all very solid, the strength of your team. Your starting pitching is suspect though, carlos is a stud, roy is a stud, but the rest of your starters are average. CC will put up good era/whip but not get wins, the rest of them are middle of the pack type guys. Your closers are all just ok except Kolb who is solid and Chacon who is an accident waiting to happen.
Team should do well, should make the playoffs but I have to imagine at least one other team could take 1st place over you, if not more.
