From your post, I assume you get to keep 3.
I also don't know your league's scoring system.
But, all things being "normal", I'd keep:
the Philly "D"($)
Manning and Bledsoe?
The Colts are (believe me) on the looooong downhill slide offensively w/ Dungy, and Bledsoe (I had him this past year, too) pretty much collapsed down the stretch after a H.O.T. start, and Peerless Price is, as I understand it, a FA looking around.
My 2 cents, anyway.
