For all intents and purposes, Dennis Dixon only made one mistake on Sunday night but unfortunately for him and the Steelers, that one mistake cost them a potential victory.

Dixon’s interception in overtime set the table for the Ravens to kick a game-winning field goal in a 20-17 victory. The win helped Baltimore improve to 6-5 on the season and kept its playoff hopes alive, while Pittsburgh fell to 6-5 and has now lost three in a row.

Dixon, a third stringer making his first career start, gave the Steelers a chance to win in the second half when he broke off a 24-yard touchdown run early in the fourth quarter. He also threw a 33-yard touchdown pass to Santonio Holmes in the second quarter and had a 31-yard run called back due to a holding call.

But on the possession following his fourth quarter touchdown run, the Ravens converted on a 4th and 5 from their own 46-yard line when Joe Flacco hit Ray Rice on a 44-yard completion. The drive ended in a field goal, which potentially forced overtime with the score tied 7-7.

Take away Dixon’s interception and the Steelers’ offense played pretty good – ultra conservative, but good. It was Pittsburgh’s defense that yielded several big plays, including Rice’s fourth down reception and a 54-yard reception by Mark Clayton late in the second half that set up a 10-yard Derrick Mason touchdown. If the Steelers had limited the big plays, Dixon’s effort would have been enough.

Pittsburgh needs a healthy Troy Polamalu back in the lineup if it has any chance of making another run at a Super Bowl, nevertheless the playoffs. Without him, Pittsburgh’s defense is good but certainly not great, which has been evident the past couple weeks.
