That's because Strickland has this rather boring style where he covers up and uses quick jabs and low kicks all the time to soften up opponents. He's mainly a boxer and used to endure long fights, which is not what people in MMA are used to. They expect a lot of kicks to the head, flying knees and takedowns and none of these are what Strickland is known for.
Anyway, I'm happy for him. In my previous comment I said it's his fight and it turned out to be like that.
Strickland proves a simple defense works well while always ready to throw punches in return.
But it's not just that. People see the difference about Costa as he isn't the same after he lost against Izzy. He used to be a finisher. The confidence is just not going back easily and maybe one would be very careful already when the fighter experienced the same level of punishment.
I don't know if your confidence would still be back if someone did this to you publicly. LOL
Yes, and it was literally with the basics that Strickland became the champion of the category against many people. You can say what you want about him, but the way he fights, attacks and defends is unique, literally.
