It's been an interesting year in WWE full of ups and downs, so as we hit the month of December it's that time of year where we look back on some things that happened in 2014 while also looking ahead to 2015. This time the focus is on WWE's most improved performers of the year. The term "improved" is subjective. There are so many people on WWE's roster that you could say are in a better sport right now than they were a year ago, but is it because they improved or simply due to the fact that they were given more of an opportunity? Every circumstance is different. There are guys and girls on the WWE roster that are more talented than people in PPV matches, yet they are not in a position where we could say they are improved. An example of people that should be improved are Bo Dallas and Emma. Bo was NXT Champion, got called up to the main roster, had a TV push for a few months and then he became a TV jobber. Emma is a younger wrestler with a lot of talent, but she's barely on television so how can she really improve in the eyes of the WWE TV viewer? There are dozens of others like that too. It's hard to decide who can qualify for something like this. If you look at the likes of Dean Ambrose and Seth Rollins, they are in more featured roles this year although they were both awesome already. Roman Reigns had a good year, but not sure if he really turned it up. That's what makes "improved" tough to figure out sometimes. This is a look at people that have different kinds of experience in WWE. Some of them have been in the company for nearly a decade. Others have been there for a year of two. Several of them are exclusively NXT talents right now because that's what the NXT system is in place for. Here's a look at ten of the most improved performers in WWE this year.
