This is easily the most upsetting group on the list. You can feign anger or disgust in Alex Rodriguez and company, but at least they provided us with a substantial amount of entertainment over the years. You can be upset that the guys in the next few groups didn't quite do enough to make the Hall of Fame, but who's to say they didn't play to the fullest of their ability for over a decade?
These guys, however, were robbed from us by a consistent barrage of bumps and bruises.
Hamilton's well-documented struggle with drugs and alcohol not only delayed his arrival in the majors by several years, but would likely be cause enough for the BBWAA to decide he's not worthy of being part of the prestigious Hall of Fame. And whether or not it's connected to past substance abuse, he's had difficulty staying healthy.
Ramirez has missed at least 13 games in nine of the past 10 seasons (including 2013), playing in just 81.7 percent of possible games over that stretch. Teixeira has missed a ton of games over the past season and a half. The more that comes out about his wrist injury, the more I doubt if he'll ever play anything close to a full season again.
Peavy has missed at least seven starts in five of the past six seasons. Lackey struggled through 2011 before missing all of 2012. Beckett never had any substantial trips to the disabled list, but only had two fully-healthy seasons in his career and posted a 5.01 ERA in the season in which he made the most starts.
Last, but certainly most disappointing, Santana only had five really healthy seasons in his career, dominating everyone in his path from 2004-08. Through the end of June in 2012, he seemed to be experiencing a career renaissance that could push him back towards the Hall of Fame. He then made five straight horrible starts and hasn't been seen since.
