Flacco's been playing at an extremely high level for the last month and a half while San Francisco's defense, for as well as it defended against the pass for much of the year, has struggled against the pass since the latter part of the regular season. Tom Brady threw for 443 yards against the 49ers in Week 15 and Russell Wilson threw four touchdowns against San Francisco a week later and the 49ers have now allowed 653 yards and five scores through the air in two playoff games. Flacco, meanwhile, has thrown for an average of 291 yards per game in the last four games that he's seen a full workload. He's thrown 10 touchdowns without an interception in those four games. In the playoffs, he's averaging nearly 17 yards per completion and he's completed 15 passes that have gone for gains of 20 yards or longer.
