The Dolphins list of offseason needs is a long one, beginning with a head coach.

But the guy who’s sitting in that chair at the moment might add another couple of items, namely a toothbrush and some mouthwash.

Of course, interim coach Dan Campbell was reflecting on a loss to the Chargers that secured the fifth losing season in seven years for the Dolphins, so it’s understandable his mood was poor.

“I don’t like the taste of losing. There’s nothing fun about having the taste of crap in your mouth,” Campbell said Monday, via Patrick Maks of the South Florida Sun-Sentinel. “And that’s what we have.”

Of course, much of this was coming, when they fired head coach Joe Philbin four games into a season and replaced him with fire-breathing Campbell, who gave them a momentary lift. But the problems there transcend beyond coaching, and that’s something they can’t fix in two weeks. That mindset, apparently, has begun to stink up the locker room.

“I felt like those guys got themselves up physically to go,” Campbell said. “But mentally, the focus was not there. The focusing on the details, the discipline to the details, that’s what lacked.”

Again, the changes coming for the Dolphins figure to be significant, and they should be. Flushing this season might be the best idea for all involved.
