I don't think thats a bad team at all. Its just that you have a whole lot of players who are elite, but playing like crap.
C- Dioner Navarro - Playing better than almost all catchers.
1B- Kevin Youkilis - Having a good year so far.
2B- Dustin Pedroia - Decent year, maybe not up to expectations, but still decent.
3B- Jorge Cantu - Hopefully hasn't been on your team all year.
SS- Jimmy Rollins - Getting hits, but lacking pop.
OF- Grady Sizemore - Playing like crap somewhat.
OF- Carlos Beltran - No pop, RBIs are decent.
OF- Jacoby Ellsbury - Great year so far, on pace for about 120 Runs and 60+ SBs.
Util- Juan Pierre - Doesn't play often enough to be your Util unless you watch every night.
Util- Jarrod Saltalamacchia - Huge disappointment this year.
Bn- Skip Schumaker - Nice real player, but has tailed off fantasy wise lately.
Bn- Julio Lugo - Blah
Bn- Orlando Hudson - Blah with a little upswing lately.
DL- Troy Tulowitzki - Ouch
SP- Justin Verlander - Been terrible, but will turn around.
SP- Jon Lester - Has been above average even without the no-no.
SP- Daniel Cabrera - Off and on. If he keeps his walks down he's great, last start scares me.
SP- Jair Jurrjens - Been great so far.
RP- Jonathan Papelbon - Excellent so far.
RP- John Smoltz - Ouch
RP- BJ Ryan - Excellent addition to Papelbon.
P- Jonathan Broxton - Hasn't lived up to the hype this year. Good player though.
P- Chris Young - Decent. Hurt though.
P- Clayton Kershaw - Will be great.
Bn- Clay Buchholz - Could be great.
Bn- Pedro Martinez - Should be at least servicable.
-To me it looks like you have a decent amount of good players, but it seems like at the time being you seriously lack pop on the offensive side which is killing HRs, RBIs, and OPS. Thats almost half of the offensive cats. Verlander has been no doubt killing you just as he has plagued most of the owners. Your pitching at the time being is really hurting and is not overall impressive outside of the Closer spot. However, you didn't mention how big the league is and if two closers are enough to compete in saves.....I would assume it is not. Until Beltran, Sizemore, Verlander, and Rollins come around.....or at least most of them you will be hurting. If Kershaw is stellar and Pedro is Pedro or old, you will be okay until those other guys turn it around.
I would just say be patient and see where you are at in about 6 weeks. If you are still really hurting, just sell one or two of your big names for "this year" players and worry about next year next year. Good luck!
