Time is right for Raiders to fire Dennis Allen

The only thing perfect about the Oakland Raiders? It is the perfect time to make a coaching change.

Speculation about coach Dennis Allen getting fired has been high for weeks and is now off the charts after another lopsided defeat. The Raiders were throttled by the Miami Dolphins, 38-14 in London on Sunday and fall to 0-4.

Oakland, which may have lost quarterback Derek Carr for a few weeks with ankle and knee injuries, has lost 10 straight games dating back to November. And the 10-game span is the longest current losing streak in the NFL. The Raiders are 0-4 for the first time since 2006 and 8-28 under Allen.

Allen told reporters after Sunday's game he is not worried about losing his job and thinks he will remain the coach.

But it wouldn't be a surprise if Oakland owner Mark Davis has other ideas. The Raiders will fly home for their bye week. With a winless team, Davis may feel compelled to make a change. He let it be known he wanted to see the Raiders be competitive this season. That has not happened.

The Raiders have been playing a lot of garbage time in the second half. Their first two games, against the New York Jets and Houston Texans, were not competitive. The Raiders played well on defense at New England last week and the team flew to London feeling good about itself.

The Raiders were confident because they spent the entire week in London, adjusting their body clocks, while the Dolphins flew to London early Friday morning. Plus, the Dolphins seemed to be in disarray the past two weeks.

However, the Dolphins completely controlled this game. The Raiders took a step back to their noncompetitive tendencies. After a strong first series, in which they scored a touchdown, the Raiders fell flat both on offense and defense. The Dolphins scored 38 unanswered points before the Raiders scored a garbage-time touchdown. The Raiders have scored a total of 51 points this season. All but 23 of those points have come when the game was already decided.

Garbage-time success was not what Davis had in mind this season. The Raiders finally had a clear salary cap and a full draft class. Oakland added several veterans and its brass thought it would be competitive, but it hasn't happened. The Raiders were hoping to have success before the bye because the games against the Jets, Texans and Dolphins all appeared to be winnable. The Raiders' schedule stiffens significantly following Week 5.

The fact that the only good Oakland has done in a quarter of the season is one good defensive game could cost Allen his job. Sunday's defeat was the ninth of the Allen era in which the Raiders have lost by 20 or more points. That's a quarter of his tenure.

The only question Davis may have for himself is if he thinks firing Allen now will spark his team for the rest of the season. The top interim coach candidates would be offensive line coach Tony Sparano, offensive coordinator Greg Olson or assistant Al Saunders.

Making the Raiders' situation even dire is the fact Carr, a promising rookie, is likely out for a few weeks. Carr said after the game he had a high ankle sprain and MCL sprain in his knee. While recovery times vary, Carr could miss up to a month. He was replaced by No. 3 quarterback Matt McGloin in the third quarter Sunday. Backup Matt Schaub has been away from the team the past two weeks dealing with a family issue.

So, if McGloin is the starter for the next month, the Raiders will likely struggle whether Allen is fired or not. If Davis is going to make the move, the time is now. Surely, Davis will spend the long flight home thinking of exactly that.
