The Raiders surged to 6-4 with a three-game winning streak just after midseason but had a tough time sustaining that success. They lost control of their playoff destiny in an ensuing four-game slide, finishing the season with five losses in their last six games.

There were plenty of reasons why the Raiders ran out of gas. They always were better than the sum of their parts, clearly talent deficient in certain areas when compared to better competition. They also suffered a series of setbacks, from Antonio Brown's meltdown to Vontaze Burfict’s suspension to a series of injury setbacks the Raiders weren’t deep enough to survive in the midst of roster reconstruction.

Head coach Jon Gruden threw another issue into the mix that cropped up during the Raiders’ poor finish.

“I think the cold weather is one thing,” Gruden said at his season-ending press conference. “We got to prove we can exorcise that demon. We got to play better in the bad weather.

“I remember when I went to Tampa Bay, they hadn’t won a game in the history of the franchise in temperatures that were below 40 degrees and every single game we played that’s all we heard. And we are going to continue to hear it, hear it and hear it until we prove as a West Coast team we can go out on a cold day and win.”

The Raiders have lost seven straight games kicked off at below 40 degrees, including three late in the 2019 season. They have lost 11 straight under 50, a brutal stretch that does have to be remedied if the Silver and Black wants to orchestrate a successful run into and through the postseason. Had the Raiders been in the AFC playoffs this year, two of the four conference playoff games had been waged below 50 degrees.

“I think it’s a combination of a lot of things -- talent, better coaching, experience, toughness,” Gruden said. “I don’t know. Travel plans, pregame meals, something. We’ve got to play better. We got to get wins on the road and we got to look forward to playing when it’s hot, when it’s cold, when it’s nasty, when it’s awful. You got to learn to love the misery and maybe we got to leave on a Wednesday next year and get acclimated to it. I’m not making excuses, but that’s one theme is pretty obvious and noticeable. We got to play better in lousy weather and we got to play better period in all three phases.”

Gruden also mentioned this point a day after the season finale, where they lost to Denver in the cold.

While fans typically blame Derek Carr for this issue due to his 2-11 record playing at less than 50 degrees, this is a team-wide problem.

“I know that the cold weather doesn’t affect Derek Carr," offensive coordinator Greg Olson said. "We practice in cold weather, he practices without sleeves, he throws the ball very well. He makes appropriate checks when in practice.

“I know the quarterbacks, generally, they’re always evaluated on wins and losses. No matter what kind of weather it is, they’re always going to be judged on records. We don’t read too much into it.”
