I enjoy David Starr, but come on really?
here are the guys I would nominate-
Roman Reigns- case has already been made above.
AJ Styles- Multiple great matches, was even fun when relegated to the US title, highlight of every show he's on
Kazuchika Okada- An incredible title reign. Even if the Dome match wasn't your cup of tea (which I can understand), this was the year he put it all together. The defenses against MiSu, Shibata, Ibushi, and Cody were all awesome. Had a great G1 run as well. Each title defense was a completely different match with a different story. He's became such a great white meat babyface and I can't think of anybody currently with a better babyface comeback or who is better at fighting from underneath.
Kento Miyahara- His Triple Crown matches have been incredible, he's responsible for keeping All Japan alive and interesting
Tetsuya Naito- Possibly the most compelling title chase I've seen since Daniel Bryan 4 years ago. Solid matches, a great gimmick, he's slowly turned from a heel to the hottest baby face in the company over the last 18 months or so during the title chase.
Kenny Omega- I enjoyed the matches with Okada. I know I might be in the minority around here with that opinion. I enjoyed his G1 run. and I find the current feud with Jericho to be the most fun feud I've seen in a decade.
