I might be mistaken, but I believe at least Florian is the top contender for the belt due to his domination of everyone in that weight class. I don't recall him taking more than 1 loss which is more than I can say for anyone else who's been fighting in or near that weight class in the last year. I think the overall strength and will of Sherk makes this a good fight to watch which probably came into the decision process.
I'd love to hear your thoughts on who else deserves the shot more. Please list the fighters in the light weight division that you think are better than Florian.
