Ben Roethlisberger is hardly a guy to root for, unless you're a Steelers fan.
But it's not right to call him an "honorable mention" in the Bad Quarterback League. Andrew Sharp says, "He's the king of throwing for 110 yards, one interception, and no touchdowns and still somehow getting the win."
You don't get to the Super Bowl three times, winning twice with two defense-minded head coaches, if you're not very good. Say what you will about the traditional NFL passer rating, but you don't go over 95 six times in a 9-year career and be a bad quarterback.
The only "knock" on him is that he's qb'ing a run-based offense, thus has thrown for 4,000 yards only twice.
But it goes to show that when he does throw, he's very efficient.
It could be that Roethlisberger is overrated to some degree, and might be less successful working for less competent franchise. But he's obviously one of the ten best in the league, not one of the thirteen worst.
