Long time listener, first time caller.
I'd start the season with the D as is, BG never rushes into anything anyways. If anyone was to go I'd package Ribs and even Ryder for trade bait. We only need one undersized centre on this team (I vividly remember LeCavalier tossing Ribeiro around like a bag of laundry in that playoff series). Don't forget Bulis and Hossa can both slide into the middle no probs, and Perezhogin/Latendresse will make Ryder a distant memory in two years.
