2-3 Team, Looks Amazing on Paper...

[NY COWBOY]

So I'm in a keeper league where I've been wondering if I should start selling a guy or two just for a change of pace. The team looks awesome, but I've lost 3 straight after starting 2-0, coming off a championship year. Tell me what you think...

QB Tony Romo
RB Arian Foster
RB Darren McFadden
WR Calvin Johnson
WR Andre Johnson
TE Jimmy Graham
W/R Frank Gore
W/T Kenny Britt

Also, I traded away my first round pick last year for Mike Turner and Larry Fitz....

Does anybody think I should get rid of one of my underachieving superstars? Or should I just sit on my team and hope for them to rise up to expectations?
