This would be my all time Yankee team from 1946 to the present. I do it somewhat differently in that I base making the team on single season performance rather than career, and also the players that make the best "team".

I do this for every MLB team and the players that make up each team are based on many-many millions of computer simulations " best vs the best" . Choose a team of your own from the same time frame and play them against the above team. It's fun and hopefully you will learn something.
