Tampa Bay’s Raheem Morris is taking it upon himself to fix one of the NFL’s worst defenses.

The first-year coach added defensive playcalling to his duties Tuesday, demoting veteran defensive coordinator Jim Bates after a 38-7 loss to unbeaten NFC South rival New Orleans dropped the Bucs to 1-9.

“I feel like it’s my responsibility. I feel like I have to do it,” said Morris, who at 33 is the league’s youngest coach. “I feel like it’s what I’m supposed to do as a head coach.”

The Bucs are 26th in the NFL in total defense, allowing just over 378 yards per game. They’re last in rushing defense and have allowed 294 points, the second-highest total in the league.

Dallas upset with officials

Dallas Cowboys coach Wade Phillips is tired of hearing the league apologize for officiating mistakes.

Dallas was on the wrong end of incidents involving replay in its past two games. In a loss to Green Bay, the Packers were not penalized for throwing a challenge flag when they were out of challenges, and in a win over Washington on Sunday the crew made a series of errors on the same play.

“Well, I mean, it shouldn’t (happen),” he said. “That’s what they’re paid to do.”
