Roman had dead reactions, you just ain't paying attention. When he got reactions, it was at Royal Rumble and beyond.
Go on the WWE Network and watch his singles competition in 2014, and tell me he had reactions. Because from what I remember, he didn't have reactions as a singles competitor. He wasn't exactly what you call a rising star. He was in The Shield, but that's about it. At that point, that's all he had going for him. The fact that he was in Shield. Rollins, however, he had this little spark with the crowd at the time. And when he turned heel, that's when Rollins had a nice heel run, not the best one, but a rising star to it. Ambrose? He had his own thing, but he has never been popular, the only time he ever gotten pops it was when he did a good thing. Most of the gimmicks they gave him, fell flat on its face until he won the IC title. This is the pattern I've been getting at this whole time. Ziggler, Ambrose, Rollins - they all won championships and sat on a rocket to being recognized by fans. So, if Carmella wins the Women's championship on Smackdown, and she does good things around that win... that reaction will be similar to what the USO's are currently having.
Well, calling someone's opinion, or ideas 'ludicrous' isn't exactly... civil. It's like calling someone stupid.
