Rusev gives us all, as fans, what we want and miss from monster heels.
He doesn't do the head-shake when he's staggered.
He tells a story in the ring using body parts.
He sells limb-specific injuries during the match and even afterwards.
He shows attention to detail with his in-ring psychology.
He reacts as you would expect when he's thrown a curve ball (see: flag not coming down all the way)
He's really the total package when it comes to enjoyment. I don't know if there's any wrestler I want to see more than Rusev. He's wonderful, and I don't mind his streak coming to an end because it's served its purpose - it helped get him over, it's helped escalate his standing to a legitimate main eventer, and he will continue to be fun to watch.
Rusev is one of the best examples of what I want to see in the future, and I'm LOVING him in the present. Rusev is the start of the next big wave of excellence that we didn't know NXT was building when he was there. What a great talent.
