Should I make this playoff push?

[cincyinco]

Some backround:

Diamond Mind Keeper League - based on projections.

Proposed deal:

Yankees receive: Matt Cain, Adrian Cardenas
Reds receive: Roger Clemens, Jay Bruce

Both teams are legit WS Contenders. Obviously pluses and minuses for both teams.

This would give me(the reds) a rotation of:

Halladay, Clemens, Papelbon, Vasquez, Mussina

I get a lot older, but Cain hasn't been simming well this year for me, with a plus 5 ERA, and it doesn't look to come down too much even though his projection is much better than his performence. Gives me a better 1-2 punch in the playoffs, but big questions beyond this year as papelbon also will lose his SP projection.

I dont have as much SP depth as I used to having traded some of it to acquire other talent... but getting Bruce would also allow me to slide Ichiro to CF and dangle Andruw Jones for an arm.

Should I do it? Would welcome other's perspective. My gut says go for it, the back of my head tho is typically thinkin long term. I've been a "contender" for several years now, but have yet to make a WS appearance. Lost in 7 games last year. I'm ready to win this thing. Currently sit at 58-43, 5.5 games out in 2nd after a very slow start to the year. About 2 weeks before the AS break I was 13.5 out, and caught up to 4.5 at the break. Any comments are appreciated.
