I agree with everything you said. Del Rio ALWAYS delivers in the ring & if it wasn't for his thick accent, would be one of the top mic workers, as well.I would say he is a more underrated wrestler, he has consistently given great matches. He just can't and won't get over, his character is to bland.
Absolutely agree, he has solid matches, technically a solid wrestler and tells a good story in-between the ropes but it's exactly like you say, he's just very bland to a degree that people either don't care for him or that they don't like him being pushed so hard. It's gotten to him doing the same thing he does every week. You could throw Sheamus in the same category, he became so repetitive and boring, I don't wish for anybody to get injured but he was one the guys who needed to take a step back.He's a great old school heel, he can be very repetitive and even downright boring at time though, which makes people dislike him.
He is a great talent that is consistently let down by lazy booking. His inability to connect with the crowd isn't doing him any favours popularity wise either, although it's not like Vince cares about that, you just have to look at his level of push for proof of that.
