His passer rating is up from his career average, as well as his average passing yards per game.
The completion rate is where it has been over the course of an eight-year career.
Only once before has Roethlisberger thrown more touchdown passes per game or fewer interceptions per game.
But it's been Roethlisberger's play, by his own admission, that's a key factor in Pittsburgh (7-8) failing to make the playoffs for only the fourth time since 2001.
"A lot of it just has to do with me not playing well enough down the stretch," Roethlisberger said. "Fourth-quarter drives or last-minute throws, I'm just not making it happen, so my best answer would be that I just didn't play well enough."
The Steelers controlled their playoff fate until their 13-10 loss to Cincinnati on Sunday eliminated them from the postseason.
Just as had happened one week earlier against Dallas, Roethlisberger threw an interception during a tie game that led to the opponent kicking a winning field goal.
Those losses joined others earlier this season against Denver, Oakland and Tennessee in which Pittsburgh not only blew fourth-quarter leads, but had the ball in the final minutes with a chance to drive for a potential winning score.
The Roethlisberger-led offense failed each time. In the season opener at Denver, he threw an interception to Tracy Porter that was returned 43 yards for the clinching touchdown.
"In the past, I prided myself and us in fourth-quarter comebacks," Roethlisberger said. "I've always said that you don't want to have them, because that means you haven't done well early in the game, but we've always been good at it. And this year, we just weren't. I don't think there's any rhyme or reason why, (but) it was just a year when I wasn't."
Roethlisberger has thrown only eight interceptions this season, but many came at crucial times. Six came in defeats, four in the fourth quarter or overtime. His first interception in the must-win game against the Bengals on Sunday was returned for Cincinnati's only touchdown.
This season, Roethlisberger's 84.4 passer rating in the fourth quarter and overtime is by far lower than during any of the other three quarters.
That would seem to be in contrast to the clutch reputation Roethlisberger has earned over the course of a career in which he has led 22 fourth-quarter comebacks and 29 game-winning drives during the regular season and also led a memorable comeback in the final minutes of the 2009 Super Bowl.
"I don't think there's any reason to go panic about it, because I've been pretty good for eight years doing it and had one not-so-good year on it," Roethlisberger said. "I think I played pretty good football, though, other than those situations."
To be fair, Roethlisberger was under center for three fourth-quarter comebacks this season. But even coach Mike Tomlin acknowledges his two-time Pro Bowler just wasn't the same in such situations this season.
"Just not making the critical plays," Tomlin said. "Not a lot has changed in terms of structurally for how we prepare for those moments and how we deal with those moments. They're not coming together for us, and I'm not going to try to make excuses in that regard."
Roethlisberger and Tomlin both downplayed the notion that the quarterback's right shoulder and rib injuries sustained in November are affecting his play.
Roethlisberger missed three games, and since he's come back, he's thrown six interceptions and four touchdown passes in three games - all losses.
"We can talk about that in the offseason, maybe, but I feel good enough to play," Roethlisberger said.
There have been times over the past three games that Roethlisberger's arm didn't appear as strong as usual and he was badly off on throws he typically makes. But there also are examples he was the same old Big Ben.
Against Dallas, for example, he lofted a ball more than 50 yards in the air to Mike Wallace to set up a tying second-half touchdown. Earlier in that game, he scrambled and avoided multiple sack attempts to find an open Heath Miller for a score just before halftime.
"The only reason we're in that game is because of his play," safety Ryan Clark said. "The only reason he had an opportunity to throw an interception at the critical moment is because he played so well to keep us close."
Still, Roethlisberger has largely built his career not on eye-popping numbers but on clutch play.
When asked about why this season has been so much different, Wallace shrugs and maintains that Roethlisberger is the same at practice and in the huddle.
"You can't be perfect every time," Roethlisberger said. "You can't be a superhero every time."
Maybe, but Roethlisberger was far from it late in this season - and as a result, the Steelers will spend January at home.
"I not worried about Ben," Miller said. "He's one of the best quarterbacks in the league - in my mind, he's still there. And I wouldn't want anybody else to be leading this team."
Notes: The Steelers placed Miller, CB Ike Taylor and RB Baron Batch on injured reserve Wednesday and signed TE Jamie McCoy, S Damon Cromartie-Smith and LB Marshall McFadden to the active roster. Miller, who tore knee ligaments Sunday, will have surgery Wednesday.
