Any thoughts to improve? Serious $$ league

[Jack-In-A-Box]

Realllllly would love to win this as last year I missed the playoffs due to tiebreaker. Any thoughts on how I could improve would be greatly appreciated. I know I took some risks but I've always loved being the guy that takes risks on players and watch as they most often times payoff. CBS sportsline 10 team league- Standard points based H2H.
Hitting- 1pt Single, 2pts Dbl, 3pts Triple, 4pt HR, 1pt BB/R/RBi, 2pt SB

C- I.Rodriguez
1B- R.Sexson
2B- B.Boone
3B- E.Chavez
SS- M.Tejada
OF- G.Sheffield
OF- J.D. Drew
OF- R.Hidalgo
U- P.Nevin
Bench- L.Berkman, Mike Sweeney

Any 7 pitchers start each week- 10pts W/S, 1pt K, 2pts IP, 5pts CG,
- .5pt Hit/BB
SP's- J.Santana, M.Mulder, T.Hudson, L.Hernandez, S.Kazmir, C.C. Sabathia, M.Morris
Closers/RP- F.Cordero, D.Graves, T.Percival, U.Urbina(insurance)

I feel like I have a real strong team but took some chances on some major injury risk type players.. Sexson, Percival, Morris, Berkman and so on. Should I just be patient and see how the season moves or try and find someone else who might help me sooner rather than later? Thinking about dumping Kazmir for Willy Mo Pena in case Hidalgo doesnt pan out like I hoped but, I'm really wanting to see how Kazmir does his 1st year.. thinking he might be special. Any ideas from anyone.. will respond in return. Thanks

I think your team could be good... or have a full collapse. Out of Sexson, Boone, Drew, Hidalgo, and Berkman, two or more won't perform or spend more time on the DL. Phil Nevin could go down with an injury, and you're hitting is done. Might want to grab some more OF depth
