I've decided to go the same route. Rick Dipietro just cost me a tournament, allowing two very weak goals. I only allowed 8 shots on goal, too. So, I'm going to try to sell a goaltender that is rated 87 overall.
Also going up for sale is Doug Weight(80), Bill Guerin(82), Chris Clark(82) and Jamal Mayers(82). I'm going to keep my defence together since they are awesome. Right now, I have them listed for 1500 each and buy now at 2500. I'm afraid that might be too much, but hopefully I can sell one or two of them without lowering the price.
