I do agree that Konecny would be no easy out for any of those names. I wouldn't necessarily favor him over them all, maybe even money against most.
I would love
to see him rough up Vanes. (and think there's an excellent chance he would)
Konecny vs. Angulo or Kirkland could be FOTY material. Trout or Molina, not so much.
Both those guys would take one look at his style and set about pot-shotting and keeping him way the hell at a distance (or swallowed in a clinch)
