It will probably come down to what you want. I learned most of this by checking the draft evals of leagues I wasn't even in. For instance, most people around here will tell you 12-13 Lebron and 66-67 Wilt are the best two seasons in the sim. For guys like Kareem, Moses, and Rodman, you can grab their most expensive season and come away happy. For a guys like Shaq and Jordan, there are a couple competing seasons depending on who you ask.
