I went to the Giants game today and got the atmosphere in the ballpark and clubhouse and talked to people and heard all the talk about how baseball should change the rules so home-plate collisions no longer will happen — even though Yogi Berra and Roy Campanella and Johnny Bench etc. etc. lived with them. I wrote my Friday column about the sadness of losing Posey, perhaps for the season, and the implications of changing rules. To read my column click here.
