At the midway point, things are heating up in this amazing and wacky 2014 season.We have overachievement and misery. We have desperation and desire. Soon, we will separate the contenders from the pretenders.Long story short, the pre sure is mounting -- especially for the men in charge.Some head coaches will earn their walking papers. Some need to hit the playoffs to survive. Some need more than just a playoff berth. Others need a miracle.Here are the coaches facing the most pre Isaiah Coulter Jersey sure in the second half of the season, presented in countdown style:9) Jeff Fisher, St. Louis RamsThere is no chance Fisher gets fired at the end of the year. And he shouldn't -- this is a really good coach.That said, Fisher is sub-.500 (16-22-1) in two and a half years with St. Louis. While you can say he's had bad luck with injuries, Fisher's decision to bank on was a mistake. And the head coach has major influence on general manager Les Snead in terms of picking players, so the roster comes back to Fisher.Even with at quarterback and left tackle out for the year, it would be nice to see some progre s in the second half, something to build on for 2015.8) Marc Trestman, Chicago BearsI picked Trestman to win Coach of the Year . That wasn't my best call.Many things are alarming with Chicago this year, including the defense and the stunning inability to win at home. But one thing is especially troublesome for Trestman: 's regre sion.The gave Cutler back in January, figuring he'd fully blo som under Trestman's watchful eye. But the mistakes are still there -- as is the inconsistency. Cutler's maddening turnovers are omnipresent.The constant finger-pointing and are a bad look for Trestman. Where is the leadership?I still believe in Trestman. But his seat could get warm for 2015 if the tank and don't show any signs of improvement and togetherne s.7) Marvin Lewis, Cincinnati BengalsLet me grab my calculator and add up the playoff wins ... Zero! Still zero.OK, so the fact that Cincinnati somehow finds itself in first place, despite injuries to key players like , is a credit to Lewis. (Even though Cincy benefited from, in my opinion, a push into the end zone and a flop in the crucial final minutes .) But the heat is still on. With the overall talent on this roster, the need Eric Kush Jersey to not just make the playoffs, but do some damage once they get there.We've always put the pre sure on , but here's a simple question: Is a big-time coach? Do you trust his game management in the playoffs, based upon precedent? I'm going with no on both queries.At what point is Lewis held accountable?6) Doug Marrone, Buffalo BillsI'm on record . I think he's a very good coach and the 5-3 are right in AFC East contention.The went for it in the offseason, dealing away their 2015 first-round pick to get . I loved the move. So far, it has worked out just fine. Then Marrone made the risky decision to bench his first ever draft pick, , for -- and that has paid off brilliantly, with Orton posting a 3-1 record and 104.0 quarterback rating in four starts.But the must continue to win games, especially with a new owner in Terry Pegula. That alone puts pre sure on Marrone. is no cake walk, either, with road games at Denver and New England, as well as home contests against the and .Here's hoping Pegula keeps Marrone. The coach deserves it.5) Joe Philbin, Miami DolphinsIt was kind of surprising that Philbin even made it to this season, after the Richie Incognito situation and the ' late-season meltdown to mi s the playoffs.But Miami has looked like a functional NFL team in the first half. And ever since prior to , has been a solid and reliable signal-caller.Still, it's not at all hard to imagine owner Stephen Ro s making a change if Miami Jason Peters Jersey mi ses the playoffs for the sixth straight season. And with the omnipresent rumors that and the are headed for a divorce, remember that -- even while he was still employing .4) John Fox, Denver BroncosSchein: The team to beat in 2014Adam Schein explains why the are clearly the cream of the NFL crop -- and will deliver on the game's biggest stage. Fair? Unfair? Here's the truth: Denver is the best team in the NFL. And with that being the case, there's one simple expectation in the Mile High City: a title.And the have the players to get it done -- just like they had the players to get it done when and the two Januarys ago.There is mounting pre sure on Fox, who didn't exactly dazzle with in-game strategy in .3) Jason Garrett, Dallas CowboysThe eradicated a lot of the good vibes established in the first two months of the season when they foolishly -- and irresponsibly -- reinserted their franchise quarterback into . , of course, was taken to the Josh Blackwell Jersey locker room after . You know, the same who's undergone two back surgeries in the last two years. A quarter later, the inexplicably put him back in the game. Judging by how , I put this is on Jerry Jones, not . But, if things go south, Garrett's the No. 1 scapegoat candidate.There's always pre sure on Garrett anyway. Now, after Monday's home defeat, and with Romo's health and availability in doubt for , the pre sure ratchets up even more.The second half of isn't easy. And if Romo isn't healthy, that's a gigantic problem. Ten wins doesn't clinch anything in the NFC this fall.Simple math says at least two of these teams will mi s the playoffs: Dallas, Philadelphia, Detroit, Green Bay, Arizona, San Francisco, Seattle. Can you imagine Jerry's rage if the are one of them?2) Mike Smith, Atlanta FalconsDid you see poor 's face when , giving the in London? explaining why Atlanta needs to go in a different direction. That was before Smith's surrendered a 21-point lead in unfathomable fashion!1) Rex Ryan, New York Jets should have been fired . He was attached at the hip with general manager Mike Tannenbaum, so when the canned the latter, they should've done the same with the former.The mi sed the playoffs last season, but they were better than most anticipated. Consequently, the players dumped Gatorade on Rex after gave them an 8-8 record -- the single goofiest and least-worthy Gatorade bath ever.Now, the are 1-7. They are embarra sing. It's not all Rex's fault. General manager John Idzik, from the draft to free agency to , has been horrendous at his job.Next up for a coaching jobConor Orr takes a look at five a sistants -- like Rob Ryan -- waiting in the wings to get a head coaching gig next offseason. But Rex is a defensive coordinator. He's not a head coach. He isn't a manager. The same mistakes are made over and over again. Rex can't figure out the quarterback position and seemingly ignores the offensive side of the ball. He's whiffed on game-day rosters, Jaylon Hutchings Jersey from having an injured Tim Tebow as 's backup in to playing -- and setting back -- a hobbled this year.Credit Rex for his two AFC Championship Game appearances in his first two years on the job, but this tenure has run its course.It's over, Rex.Follow Adam Schein on Twitter .
