4. Mark Henry
Mark Henry has been in the WWE since 1996. He has been with the company longer than the character Kane has existed. He has had a 20 year career filled with multiple World championships... whoops, that's not correct. Henry has been injured so many times. He hurts himself at least twice a year at this point. He has been out twice in 2013. This doesn't work. Injury prone wrestlers never make it to their full potential. They can't. Henry should be a multi-time World champion. He should be a former WWE Champion. His promo in early June 2013 was the work of a master. He can talk. He can work. He can do it all. But the WWE can't trust that he won't fall down weird at a house show and miss six month again. They can't put the full weight of the MACHINE behind him. (We'll get to World champs who get injured in the next slide) I am not taking away from Henry his success with The Hall of Pain, his World title run or or the fact that this is, in fact, what he does. It is what he does...some of the time. A healthy Henry is a great Henry. Sadly it is something we've never really seen, and it's deprived us of something potentially awesome.
