I think the Flyers would come out ahead in that trade, but really dont see it happening because of the cap.
Markov is a good defenseman, better than most of the Flyers defenseman if not all. (Pronger has been good in the playoffs, but the regular season..no way)
Price is a project goalie with lots of potential...maybe even a star.
Carter is a top six forward, but is often injured and does not play a physical style.
Coburn is average at best. He is playing well in the playoffs, but I still maintain he is average..
Markov is not better then Pronger.
Price is not a star.
Carter is not often injured. This was the first year he had any major injury. He can play physical when pushed too, and is a better talent then both Price and Markov.
I would take Coburn and his potential to be a top two, and his age, over an aging injured Markov any day. And I may be biased, but Coburn's game turned around when Laviolette was hired. I dont think its a coincidence.
