You sir, then are putting people in just based off numbers. I am a fan of baseball, but I feel the HoF is for the best of the best and not just based on stats. Do you honestly consider Biggio, Blyleven, or Jim Rice the best of the best?
I guess we have a significant opinion on the definition of "Best of the Best".
My opinion is - the Hall of Fame should include the best of the best "Baseball Players" during whichever era they played. I do believe that metrics are merely a tool as a measuring stick -- however, I also believe there should be other intangibles that go into "Best of the Best". Your intangible seems to be "Did I want to watch them?"
To answer that question -- for Biggio, hell yes, I loved watching him play. During his career, he was the epiotme of what I believe Baseball is all about. He gave his best effort every play of every game. He played at least 155 games half the seasons he played. He also had 3 seasons that he played 162 games. That is unheard of in modern baseball. That said - I am obviously an Astros fan and am unabashadly biased.
However, I truly believe if Biggio had played his entire career with the Yankees, Cubs, or Mets -- his HOF candidacy would be evaluated completely different than what it is today. 1) I probably wouldn't have wanted to watch him much, therefore I devalue his accomplishments as a MLB player, and 2) Larger media would accept his play as "Best of the Best" consideration.
