Volkan has turned me into a fan, especially with how big of a shit show LHW has turned into, but I agree with you. He obviously has a ton of potential and is great in the standup, if he fights/beats either of the two guys you named then I can see him getting the belt and holding on to it for awhile.
Preferably he gets Glover down the road, I would like to see gus because of the standup battle that would be but gus might be a little too fast for Volkan, Glover is a better matchup for him as long as he can keep it standing.
