The only reasons that I can think of as to why any of these players doesn't make the HOF on the first ballot are: Bonds - Steroids Clemens -Steroids Sosa - speculation of steroids Johnson - short of 300 wins Piazza - poor defense Biggio, Maddux, Martinez, Glavine, Smoltz are all cinch 1st ballot HOF. The numbers would make all 10 of them 1st ballot HOF. Johnson - 4653 K's (soon to be #2 all-time) Piazza - arguably the greatest offensive catcher in the history of the game
