ESPN.com has a poll up, asking people who they'd rather have on their team, Vick or Roethlisberger. I thought it was an interesting questioning.
I think to answer the question, you need to assume that your team's starting QB had a season-ending injury. If you had to pick one guy to fill in, who would it be?
I think Big Ben is the better QB. He's won two Super Bowls, he's a very good pocket passer, and he's got respectable mobility. Vick is more dangerous with his legs, and has made it to the Super Bowl, but he just doesn't have the passing pedigree.
At the same time, there's the morality issue to weigh. Vick was involved in torturing and killing animals. Big Ben is alleged to have raped at least one, and potentially multiple, women. To me, both guys are scum bags, but Big Ben's alleged crime is worse. However, he was never convicted, or even charged.
In the end, I just don't know. I guess if my team was mediocre, I'd prefer Vick, because he can make more things happen on his own. If my team was a Super Bowl contender, I'd probably hold my nose and take Roethlisberger.
