I am willing to say that it is possible that he will become comparable to Austin or Hogan. Like I said: Given his look, his charisma, his determination, his smartness, his momentum and room to improve in the ring, I think he could be the next breakout star. At least one other echoed my sentiments about Batista not being the one that will ruin his own rise. I think that given a fair chance, what the qualities mentioned above, he can make it.
That said, your feelings that fans are latching onto Bat due to desperation is the yin to my yang of some other fans being negative about his push due to cynicism. In the end, all we can do is make educated guesses, and my guess is that Batista has a better chance than anyone right now. If I am proven wrong, then I am proven wrong.
