Rating players using the WIN METHOD evaluation method is reasonably simple. The results will give you the best of the best of the greatest players in the game. I will claim one caveat however. It is near impossible to compare players of different eras reliably or fairly against each other. It is best to use the WIN METHOD to compare players of the same era or time frame. Different eras had different rules, ballparks were different, the introduction of more teams and the playoff system, there were no Negro, Latin, or Asian players during many eras. Equipment was different, the pitching mound has been altered, etc.
One thing is positive and undeniable (except by stat frauds), is that the greatest of the great players always and consistently helped their team to success and championships. Not individual misguided personal stats, but for the reason the game of baseball has been and is played. The things that determine the greatest. Wins and winning. To be able to determine the greatest of the great players, one only needs to go to the record books and find which players over their careers and eras helped their team to the most playoffs, pennants, and World Series Championships. Rate players by their respective role to each players team. Compare starting position players to other starting position players. Compare pitchers to pitchers, relief pitcher to relief pitchers. Backup infielders to backup infielders and backup outfielders to backup outfielders. Use common sense and always ask why. Why did these players achieve for their team more than others with greater individual stats did for their team. One gigantic WIN METHOD reason, they played for the success of the team, not their individual statistics. Winning was paramount to these greatest of the greats. Their character and will to be the best made them willing to sacrifice individual stats in order to help their team win. There you have it WIN METHOD fans. Take the stat frauds with a grain of salt, look them in the eye and ask them just how their individual stat guys could lose and still be the best. There answer will usually be, it was the players team mates fault.
