That's part of the package: it's deliberate. What we have in our midst is an old-style villain. Many folks don't appreciate the guy whose lineage goes back to Gorgeous George, Buddy Rogers and Ric Flair. These guys were flamboyant, obnoxious, overconfident and flashy. They lorded their material wealth over the rest of us and played the part of a guy who is universally hated even as he proclaims to be universally loved. Alberto Del Rio is heir to all that.
A necessary part of the persona is that the guy has to really know his way around the ring.....and Del Rio measures up. You might not like his wrestling style, but it fits the old-style persona so very well. Each of these guys delivered the goods once the bell rang, leaving the trappings and adornments behind (in Del Rio's case, it's a set of car keys

).
I think Del Rio is a terrific ring technician and a refreshing change of pace from the modern-day brawlers we see every week.......and as far as I'm concerned, the more obnoxious he acts, the better.
After last night, don't you want to see John Cena clean his clock?
