Comebacks can be a wonderful thing. Eddie Guerrero's comeback from drug addiction and despair in spring 2002 was inspirational. Shawn Michael's comeback from what was thought to be a career-ending back injury was breathtaking. Ric Flair's triumphant return in 2001, hair-raising. Yes, there have been plenty of awesome comebacks in sports entertainment history, when great performers overcome the odds to return and are then as good, if not better, than they were during their 'best' years. Indeed, Shawn Michaels and Eddie Guerrero were arguably better than in their primes after their comebacks in 2002 and Steve Austin had his best ever in-ring year in 2001, a year after he was written off by some. For every comeback worth celebrating, however, there have been comebacks that have left us scratching our heads and asking 'why?'. The intention was good, but the execution left little to be desired and, in some circumstances, these comebacks only succeeded in eroding the memory of the performers' pasts. It could have been down to any number of things from poor timing, to the audience having moved on, to the performer not being up to the task. Whatever the case may be, most fans would have rather the following ten had stayed out of the limelight and away from the squared circle.
