Not a bad list, especially from a young guy who didn't see a lot of them play. These are some I would include that he doesn't: Mike Haynes & Paul Warfield come to mind but overall he did a pretty good job IMO.
Obviously I would rearrange the rankings some but it wasn't bad. He didn't show a lot of bias which is very difficult to do. It also appeared that he was trying very hard to get a good covering of different positions and eras.
I started a thread several years ago on another forum where we could post our all-time 60-man team. It was pretty interesting to see who people picked and why. My own team was the best of course
but others had some very well thought out selections. It wasn't based solely on who you thought were the best players at each position but who could function together as a team. It wasn't just a ranking but a TEAM you were putting together of any players from any era in their primes. Pretty cool if you ask me.
Anyway, a good list overall.
