A little before my time, so I have no personal anecdotes to share or anything like that, but a reasonable case can be made that he's the most underrated catcher on this list. A very important component of the Tigers' success in the sixties until the mid seventies.

The best catcher of the 1960s. Why is Freehan not in the hall of fame? Appeared in 11 All Star Games.

The best catcher in the American League from 1963 to 1974. Defensively he was Bench BEFORE Bench. Team leader who was no easy out when at the plate. Ideal type to build a team around. Suffered from not playing in a big media market such as NY or LA.
