Anyone who doubts Bob Sanders's talent and his value to the Indianapolis Colts need look no further than their 2006 Super Bowl-winning season.
Sanders missed much of the year and the Colts' defense was, to put it lightly, awful. Opposing running backs routinely gashed Indy's defense, including a 375-yard slaughter by the Jacksonville Jaguars.
Prior to the Colts' first-round game against Kansas City, many believed Larry Johnson would run wild in a Chiefs' win that would send the Colts home early once again.
Bob Sanders had other thoughts.
He came back just in time for that game, and the defense immediately improved, not at all resembling the porous D the Colts had been running out there during the regular season. Indianapolis went on to win it all, thanks in large part to the play of Sanders.
Unfortunately for Sanders, the Colts, and sports fans everywhere, he has been unable to stay healthy since then.
There are surely countless stories of potentially great athletes whose careers were cut short. Most fans can think of several from their teams who looked to be on the way to stardom before injuries left them wondering what could have been.
