SEATTLE — From the first kickoff back in September, the 49ers and Seahawks seemed destined to meet for the NFC title.Time to get it on.With the conference’s most physical, relentless defenses, adept at forcing turnovers and making opponents think twice about, well, just about anything, Seattle (now 14-3) won the NFC West by one game over San Francisco (now 14-4). The offenses, while not nearly as imposing, have the right elements for a champion: strong running games, efficient and sometimes dynamic quarterbacks, and staunch lines.Their coaches have the proper pedigree, as well. Jim Harbaugh has led the 49ers to the NFC championship game in all three seasons in charge, making the Super Bowl last year.
