It's Peyton Manning's comeback season, so it's understandable that everybody wants to talk about him, but what about the quarterback on the other side of this week's "Monday Night Football" matchup?
Philip Rivers was well on his way to becoming an elite quarterback before his pass protection fell to pieces in 2011, and it wasn't until the San Diego Chargers installed Jared Gaither at left tackle late in the year that we began to see Rivers return to form.
Rivers' four highest-graded games of last year, according to PFF's grading system, came in those final five games with Gaither protecting him, and those four games also included completion percentages over 70 percent and just a single interception against 10 touchdowns. That was the Rivers we expected to see going forward in 2012.
How has Rivers fared historically facing pressure, and how will San Diego's offensive line hold up against the Broncos on Monday night?
