Garland, have you been to a classic old stadiums like Fenway, Wrigley, and now deceased Tiger Stadium and Yakees stadium? Compare those stadiums to the new modern marvels like Coors Field, Safeco Field, and New Yankees Stadium and tell me there have been no innovations.
The new stadiums have the same charm and ambiance of the old classics but with better sight-lines, better food, better access, more comfortable seats, better traffic flow, better bathrooms, suites, and countless other improvements that makes going to the ballgame a real pleasure. There is a reason why a team that lost over 100 games can still draw over 2 million people.
Bats have improved greatly as well with the latest in graphite and aluminum bats. Sure, they are not used in the pros, but they get used by more people. The gloves have improved and shoes as well. Baseball has not stood still.
