6. Tommy John, Indians/White Sox/Dodgers/Yankees/Angels/Athletics
Sometimes baseball milestones, such as 300 wins, 3,000 hits and 600 home runs, are easy landmarks to decide who belongs in the Hall of Fame and who doesn't. And sometimes those arbitrary numbers are completely unfair. Tommy John is exhibit A. If he had won 12 more games, he would have easily made it into the Hall of Fame. After all, he had a 26-year career, a very respectable 3.34 career ERA, was a four-time All-Star, and he racked up the seventh most wins of any left hander in MLB history. Of course, it's also worth noting that midway through his career, John suffered an elbow injury that would put him on the shelf for a year and a half. He was the recipient of a radical new surgery which took a tendon from his right forearm and placed it in his damaged elbow (now known as Tommy John surgery). Not only did he have no idea whether the surgery would be successful, he had to completely revamp his pitching style to put less pressure on his elbow. Despite this, he won 164 games after the surgery... one less than first-ballot Hall of Famer Sandy Koufax won in his entire career. His 288 wins are the most of any pitcher not in the Hall of Fame. He belongs in Cooperstown.—Johnny Goodtimes (AP Photo/File)
