Yea, I've been surprised at his impact (or lack there of) since returning. He had a ton of momentum approaching Mania 28 before that injury, it's a shame he didn't pick up where he left off. He's being utilized as a playing chip lately, not as a hand of cards. By that odd analogy, I mean he is acting as a filler - putting on some great matches - but none of them contributing to a storyine he's involved with.
When those promo vids for him starting popping up, I was really pleased to see they were making a big deal about his return. Then he just popped up on a routine Smackdown and didn't make much of a splash. I expected him to get involved in an upper-card feud almost right away. I would've been really excited to see him pop-up at a PPV and destroy Sheamus post-match. Hopefully they are saving that feud for the near future.
Oh well, he looks great since his return and hasn't lost a step in the ring or on the mic. He'll be main eventing eventually.
