Rock Moore - With 3 Most Valuable Player Awards, 10 All-Star appearances, 10 Silver Slugger Awards, 612 career HRs, .995 OPS, all while playing more innings than anyone else behind the plate. Moore is a HALL OF FAMER. In fact, he's one of the Hall of Famers that the other guys in the Hall want to get their picture taken with so they can show their grandkids that they knew Rock Moore.
Rico Perez - 2 Cy Young awards, 6th most innings pitched, 7th in quality starts. For me, he gets the nod over Steve Daly.
Matt Michaels - 2 MVP awards, 8 All-Star appearances, 6 Silver Sluggers, 2 Championships fill up his awards page. Michaels has the most innings played in CF thus far in the world. His offensive numbers as a CF are outstanding.
Russell Millwood - In the "non Rock Moore" category of catchers, Millwood might be the best. His 630 homers are the most for a catcher, he is 2nd in Runs Created for catchers.
Harry Martinez - 2 MVP awards, retires as the all-time leader in HRs, second in runs batted in,fourth in runs created, fifth in walks, sixth in hits, only a total fool wouldn't list this guy as a hall of famer in his first season of eligibility for the Hall of Fame.
These are my choices, but great arguments can be made for deserving candidates like Steve Daly,
