NBC News national correspondent Steve Kornacki takes a look at the 49ers’ playoff odds and why their Week 15 matchup vs. the Falcons has huge implications.
The Atlanta Falcons were able to tie things up vs. the 49ers in the second quarter at Levi's Stadium on Sunday after a questionable roughing the passer call on defensive lineman Arden Key on third down extended the drive and led to a Matt Ryan touchdown pass to Russell Gage shortly after.
The infraction stemmed from Key landing on Ryan with his full body weight.
San Francisco fans were not happy with the call and NFL Twitter immediately blew up.

Even CBS rules analyst, Gene Steratore, wasn’t convinced with the call.
"These are real difficult plays for the official, and real difficult for a player like Arden Key," Steratore said during the broadcast. "He just disengages from the block, and he only has one option, and that is to make a diving lunge to try to get to the quarterback. It’s different if he’s running toward the quarterback, wraps him up, then makes a decision to drive him into the ground, but to me, in my opinion, this is just a defensive player making a last-ditch effort to dive and tackle a quarterback. That’s a very hard play to penalize a defender on, in my opinion.”
