That's part of the risk, and part of the fun. You literally have no idea which version of a player you are getting unless you take a guy with only one season. It's just like preseason. Your big money free agent could be a total bust. Your highly touted rookie could step up and have a big season. Your savvy veteran point guard might have enough left in the tank for one more big year. Just like in real life, GMs build teams with certain expectations. The ones who make the right moves and get a little lucky are the ones who win. Not many gms go into a season saying "Hey, lets make this team worse" unless you think you can get Andrew Luck or you are the Florida Marlins, and with the weighted draft, there's very little incentive for tanking, unlike most progressives.
