It would be helpful to know which round you drafted these guys in - so I can really give you a solid draft analysis and let you know value plays based on where you drafted them.
Having said that, the fact that you have Pujols and Kinsler on the same team, gives you 2 legit top 10 guys and the best players at their respect positions. I have mad man crush on Kinsler. He was on every single one of my squads last year and hes an absolute beast. So solid.... Pujols is a lock for NL MVP again - and throw in Longoria, a top 3 3B - and you have a very solid catalyst offensively. The guy that I love this year on your team is Andre Ethier. I think Manny's presence will help Ethier have a bust out season and he could be a .300 - 100 runs - 25 jacks - 90 rbi - 20 steal type guy...
The rest of your offense --- Kelly Johnson is always not flashy, but very solid and should do well assuming he doesnt lose his spot in the order to Schaefer. If he doesnt, he'll be a great value play as Im sure you got him late. Peralta will give you some pop from SS, but I would also anticipate something close to a .265 average, dont expect anything close to .280. Derek Lee, who hits for a good average is a bit of a wildcard at your CI, but the fact that you have Pujols as an anchor at 1st, solidifies that slot - but, personally- Lee needs to show me that he's still got more than warning track power, and unless you got him relatively late, he could be a bit of a bust.... Napoli will hit 20 + homeruns, but also bat .240 - so temper your expectations accordingly... Fred Lewis was a nice add, and just be weary of Boche-ville, cause he'll bat him from 3rd to 7th on any given day. If Fred can add some distance to his line-drives, he could belt 20+ homeruns, which would make him a great add, but AT+T park doesnt lend itself to being a HR park, so I think .285 - 80 runs - 16 hrs- 85 rbis - 20 steals is what you are likely looking at here.
I dont think Kendry Morales or Carlos Gomez should be on your starting roster, but I dont know what else is out there. Bonifacio needs to be sold now or you're going to miss your window of opportunity. That said, he and Gomez are a good source of cheap steals and some runs, but I just dont like rostering those types of 2 category guys - cause it will come back to haunt you....You know what you have in Wieters, but I wouldnt expect more than 15-17 homeruns, and good averages once he gets called up. My advice: try and 2 for 1 some of these guys for an OF upgrade.
Regarding your pitching, Haren is one of my favorite pitchers in the league, he pitches in a great park and has a fairly solid bullpen behind him (though they have not shown in yet in 2009). He is a true ACE and in my Top 3 overall pitchers in the game; the only thing you need to worry about is the D-backs bats and the lack thereof. They have gotten out of the gates at a sluggish rate and provided zero support. Haren would be 3-0 on every other team in the league.... The other pitcher I like on your team is Bedard, and he could be a sleeper this year. I had him in Baltimore when he was a stud, and he pitches in a great pitcher park in Seattle... he'll end up being your 2nd best pitcher this year. Same with Chris Young, which is a pretty smart pick as your 5th starter. My Padres, who I expect to start sucking wind anytime now, have shown some offensive life and a fantastic bullpen anchored by Fatty. So, kudos on that pick. When right, hes nasty and a legit #2....However, Shields, Sonnastine and Lilly - I'm not big fans of and you should try to trade. Shields pitches in the best hitting league in baseball- so, while he is good - you're gonna take a beating on ERA and WHIP. Plus, his BABIP is gonna come back to earth, so I dont love him this year at all. Ditto Sonnastine.. .Lilly, is due for an off year. Granted, hes a warrior pitching for a great offense, but in summer when those balls start to heat up and fly out of Wrigley, hes gonna hurt you... Kawakami is a Japanese import rookie pitcher in the NL - which based on history, have done great their first time thru the league, so he may be a steal this year. Hes also missing tons of bats in the early going, so keep running him out there. My advice: work on trading Shields, Lilly for a good NL starter- like Cain or CBill or Vazquez. I might try hold Kawakami till June, then dish him.
Your relievers are definitely not amazing. Franklin, while he has the job now, will likely continue to share the roll and might end up with about 12-14 saves total with not very good k rate.... Gregg, who I also roster, is clearly the less dominant picher between him and Marmol. I expect Gregg to end up with about 15-17 saves total this year. Percival is old and doesnnt really have the stuff to hold down the job all year. Balfour, Wheeler and Howell all will scare him this year and steal saved. My advice: package all 3 for 1 stud closer and keep your eye on the wire for a up + coming middle reliever (leo nunez, chris ray, arrendondo type).
Overall, you're pretty solid. YOu need some OF upgrades and while your starting pitching is fine, use your depth to your advantage - and trade for NL starters.
