PITTSBURGH -- Every trip to the end zone deserves eight points, at least that's how the Pittsburgh Steelers see it.

The Steelers on Sunday set a new NFL record for successful two-point conversions in a season. Ben Roethlisberger's pass to fullback Will Johnson to the back of the end zone was the Steelers' seventh two-pointer of the season, breaking the previous record of six held by the 1994 Miami Dolphins and the 1997 Minnesota Vikings.

To keep everyone guessing, the Steelers kicked the extra point on their next score, a touchdown pass to Markus Wheaton with 10 seconds left.

The Steelers lead 21-10 at the half.

With a 70 percent success clip, why not keep going for two? The Steelers are 7-of-10 for the season. As of last week, six NFL teams hadn't attempted a two-pointer all year.

The Steelers would probably have more attempts had Roethlisberger not missed four games due to injury.

"Oh, we're going to keep doing it," Roethlisberger said in late September. "We don't practice it this much to not do it. We practice it every single day. ... I tried to tell you guys early on that we would do it, and I think you guys kind of didn't quite believe it. But it's something we feel comfortable with."

Roethlisberger is heating up with 219 first-half yards. While it isn't quite at last year's 522-yard pace against Indianapolis, he was pouring yards on the Colts with minimal resistance late in the second quarter.
