A dozen NFL coaches at risk

The San Francisco 49ers entered this 2014 NFL season among the Super Bowl favorites. They stumble into Week 15 as a prohibitive favorite to replace their head coach. They are not alone.

Kevin Bradley, sportsbook manager at bovada.lv, declined a Sunday night request to supply odds for the 49ers, Oakland Raiders and New York Jets -- because it'll be a shock if any of those three retain their coaches. Bradley did supply odds for nine other teams in some limbo, providing the framework for a discussion with high stakes for all involved.

The situations in Chicago, Miami and Washington are among the most interesting outside of San Francisco. That is where we begin my 10 takeaways from Week 14. Colin Kaepernick, Johnny Manziel, Mark Sanchez, Jeff Fisher, Jim Haslett and Peyton Manning are among those making appearances. I've also got an intriguing candidate for the 49ers to consider -- one they're already in contact with regularly.

1. It's all but over for Jim Harbaugh, Tony Sparano and Rex Ryan, but odds vary widely for some of the other coaches perched on hot seats.

Jim Harbaugh, 49ers (no odds on a return): If CEO Jed York felt compelled to apologize via Twitter for a 19-3 defeat to Seattle last week, imagine how he felt while watching a 24-13 defeat at Oakland. The silence from York was conspicuous Sunday.
