Friday evening bad-news dump. Out of the blue Dexter Lawrence Jersey , just before 7:00 p.m. ET, the Ravens let the world know that their coach who is under contract through 2019 is under contract through 2019 and he will remain under contract through 2019.Through 2019.The statement was received by most as a definitive indication that John Harbaugh ain’t going anywhere, and that anyone who already had launched a back-channel chase for his services should check themselves, lest they wreck themselves with a tampering allegation.But the confirmation of Harbaugh’s status nevertheless can be interpreted as an invitation. To make a call. To make an offer. To give the Ravens something of significant value for the coach whose name had emerged already as the most desirable horse in the looming carousel, even though he is under contract.Through 2019.“John Harbaugh will continue as our head coach for the 2019 season,” the statement announces, “and he and we are working on an extension to his existing contract, which expires after the 2019 season.”That’s not celebratory; it’s perfunctory. It’s less proclamation and more admonition to not assume that Harbaugh will be available automatically, or that he’ll be easy to obtain.It’s also designed to end the discussion and speculation, and in turn potential distraction, arising from Harbaugh’s uncertain status. Tonight against the Chargers Deandre Baker Jersey , next week against the Browns, and into the postseason (if they make it) it will be repeated over and over again that Harbaugh will be back. Even if, in the end, he isn’t.So what would another team give up for a coach who is under contract for only one more year? Well, remember when the Raiders got two first-round picks, two second-round picks, and $8 million in cash for Jon Gruden? Like Harbaugh, Gruden was under contract for only one more year.So here’s what Friday night’s statement really means: (1) Harbaugh won’t be fired, regardless of the outcome of the balance of the season; (2) Harbaugh may or may not sign an extension with the Ravens beyond 2019, the terms of which likely will be determined by the outcome of the season; and (3) call us if you’re interested in perhaps offering him better terms than we will, if you’re also willing to compensate us handsomely for the rights to a coach who is under contract.Through 2019. We're just about halfway through the 2015 NFL season and some teams have already seen their season slip away. The Miami Dolphins and Tennessee Titans already fired their head coaches and several others are already on the hot seat. Every year Oshane Ximines Jersey , it seems to be a given that at least five head coaches will lose their jobs, due to not meeting expectations, fallout with management, or the coach could even take a job elsewhere.Last year, we saw Rex Ryan, Marc Trestman, John Fox, Jim Harbaugh and Mike Smith all lose their jobs. The year before, Mike Munchak, Jim Schwartz, Leslie Frazier Julian Love Jersey , Rob Chudzinski, Gary Kubiak and Greg Schiano all get canned on Black Monday or shortly after.Remarkably, some fired coaches are able to land on their feet, as we saw Gary Kubiak get another head coaching job just one year after his firing in Houston and John Fox only had to wait a few days after parting with the Broncos to get his next job. There will be coaches fired at the end of the year and some hires will either leave fans scratching their heads. Very rarely do re-treads work, but we've seen it done a little more, hence why former head coaches will be on this list. Here they are, the top 15 head coaching candidates for 2016.
