Just looking for some help with my team, first year doing this. I've lost the last 5 weeks and would appreciate any help. Or just analyze this team, slick or not?

C- Jorge Posada
1B- Justin Morneau
2B- Jeff Kent
3B- David Wright
SS- Rafael Furcal
OF- Ichiro Suzuki
OF- Vladimir Guerrero
OF- Corey Hart
Util- Chris Duncan
BN- Ty Wigginton, Jason Bay, Willy Taveras
DL- Howie Kendrick

SP- Johan Santana
SP- Carlos Zambrano
RP - David Weathers
RP - Huston Street
P - Jake Peavy
P - Hideki Okajima

BN - Orlando Hernandez, Javier Vazquez

I just picked up Duncan after dropping Hunter Pence, and added Wigginton because Kendrick on DL.
Hardly been playing Jason Bay because of his disappointing numbers, and usually alternate between Corey Hart and Willy Taveras.
