Of course he is, I guess what some people find boring about him is that every round tends to be the same, because he lacks explosiveness. Most of his fights just fall into a pattern, with Winky coming forward, blocking, jabbing, some body punching. Its just repetitive. I don't find him boring though, he's not one of my favorite fighters but I don't think he's boring.

And its interesting, look at the Taylor-Wright fight, who was the one making the fight? Clearly Winky, yet he's the boring one while Taylor's exciting.
