This is where I completely disagree (respectfully) with you. In fact, this is where I disagree with myself for the first 42 years of my life.
I, with you, still believe that the RULE is that running QB's do not win. I have argued this forever.
In fact, just look at the Super Bowl winning QB's.
Big Ben (I just don't want to have to spell his last name)
Tom Brady
Tom Brady
Brad Johnson
Tom Brady
Trent Dilfer (need I go further)
This is the rule and the EXCEPTION PROVES the rule.
But I truly believe that Vince Young will be the exception.
Like you, I've seen the Mike Vicks do what I expected them to do, fail. They don't fail every time, they still make spectacular plays, but for game in and game out winning, and especially playoff winning, I don't like their chances.
So, I'm with you, normally.
But what I've seen out of Vince Young from the Rose Bowl to the present convinces me that he is indeed the exception. I think he will be highly successful. I think he is a winner. And winners sometimes defy explanation. They just win.
