Is this enough pitching?

[blue too]

In a 5x5 Head-to-head, final year of a keeper league.

My current staff:
R Halladay
J Smoltz
J Patterson
K Wood (DL)
P Byrd
B Radke
D Bush

Relievers:
M Rivera
B Wagner
M Gonzalez
D Weathers
A Burgos

I'm normally a big advocate of 2 stud pitchers and a strong #3, but I traded Peavy for D Wright before the season, and my offense is pretty ridiculous (C is the only position I don't have a very, very good player). I had hoped my strong RPs would give me Ks and lower my ERA and WHIP enough to allow me to lose Jake-to da-P, but now I'm doubting. Will this be enough pitching or should I begin looking to shop Thome (my Util/backup 1B) or Sheffield or someone for a stud pitcher in a few weeks?

Your pitching is solid. I don't think you need to move one of your big guns for a big SP. Another guy like Zach Duke caliber would be very helpful.
