Need Help Improving My Team [Advice?]

[CircleOfGod]

Well, I'm in need of suggestions on improving my team. I'm in a 5 team H2H, non keeper league. Yeah I know, join a real league. Just need some advice.

My roster:

C - Brian McCann
1B - Justin Morneau
2B - Kelly Johnson
3B - Ryan Zimmerman
SS - Derek Jeter
OF - Jason Heyward
OF - Bobby Abreu
OF - Ichiro Suzuki
UTIL - Vladamir Guerrero
UTIL - Manny Ramirez

Bench Spots:

Curtis Granderson
Paul Konerko
Michael Cuddyer
Carlos Pena
Michael Stanton

Pitchers:

Justin Verlander
Jon Lester
Tim Lincecum
CC Sabathia
Cole Hamels
Stephen Strasburg
Mariano Rivera

I'm alright on pitching needless to say, but I'm struggling on offense. There's plenty of options on the WW at certain positions, but I'm not sure on what I need to do. I'm currently sitting in 4th place, but soon to be in last. My MAIN area of concern is my catcher spot. Brian McCann hasn't been doing much of anything for me right now and I was thinking about dropping him for Buster Posey.

Posey has been doing really well so far, but I'm not sure if I want to hinge my season on a rookie, as I know if I drop McCann somebody is going to pick him up. Any advice on what I should do on that front?

I've been having trouble just putting up any offensive points consistently. Even my pitchers haven't been stellar to be honest. Last night, I only managed 37 points total, while the other teams in my league were at 80+ points. It's been a lot like that over the past 2-4 weeks. I'm slumping and can't seem to get any breaks.

Wish I could give you better detail on where I'm hurting exactly, but I'm hoping to get some advice on ways I could improve my team. Suggestions/Advice? I'm open to all ideas. Any advice is appreciated.

I guess in a way, I'm looking for someone to say I'm NOT out of my mind for wanting to drop McCann, but I'm thinking that MOST people would probably hold onto him and see what happens. I could be wrong. Anyone?
