Peavy coming to town?

So, it seems the Cubs are becoming the front runners for the Peavy deal AND keeping Dempster. Only problem is, according to some experts, that would likely mean we can't resign wood and go cheap on a left handed right fielder. But is that really what the Cubs need?

Don't get me wrong, I was salivating over that rotation just a couple of weeks ago. But, if I remember correctly, and I'm quite sure I do, let's play a little pretend.

The Cubs get Peavy and send away oh say Pie, Marshall, Marquis (while eating some salary), and say a minor leaguer.

With the rotation of Peavy, Zambrano, Dempster, Lilly, Harden, and Marmol closing, I'm projecting, all things being equal, the following -

95 games in which the Cubs lead or are tied after 5th inning
25 games in which the lead is lost after the 5th inning
30 games in which long relief is needed, long relief defined as starting nit he 4th inning or earlier.
30 games in which the Cubs come back/win late.
100 wins

Granted this is plus or minus 10%. But what it all adds up to is -

3 more losses in October.
1,000,000 "World Championship" t-shirts destroyed.
And at least another minute in the spotlight before wilting under the pressure...
