I mean, let's face it. The guy has been on and off the IR for the past five years too frequently. You can't build anything around him because he's too unreliable. He's done fuck all for two years. He's being paid a large sum of money for nothing.
However, he's a still a merchandise seller, though not as much as before. He's still over. And he's still capable of putting on great matches from time to time. He's still somewhat of a draw.
With the emergence of Alberto Del Rio, does the WWE really need to be putting forth the time and money into Rey, when he's really not giving it back (not being unfair, I know it's injuries and substance abuse - I actually think he's been suspended and they're keeping it quiet)? COULD they release Mysterio?
The biggest question is...IF they did, and TNA were to pick him up, how big of a help would that be for them, if at all?
