What's funny with Del Rio is that they have essentially made him, a mix of JBL, Eddie Guerro, Million Dollar Man more than Razor Ramon. I dig his character and his subtle charisma but I still haven't seen him in the ring.
From what i can see(I've just started giving Smackdown another chance over the past two months), Smackdown is now the developmental show. Yeah you got Taker, Kane, Mysterio and a few others there to fill out the top card, but overall it appears to be a testing ground.
