He was visibly upset last week when the Jaguars lost to the Minnesota Vikings, 30-12, as they fumbled twice in the first 20 seconds and fell behind 14-0 in the first two minutes. He called the performance "unacceptable."
They got off to another slow start against the Texans.
They gave up a touchdown on the Texans' first drive and then were guilty of false starts on their first two offensive plays and had to punt. And they fell behind 10-0 midway in the first period.
The loss drops them to 4-8 and means they can do no better than 8-8 and will likely have their first losing season since 2003.
But this time, Del Rio seemed more encouraging.
"We came out here and battled. We just came up short once again. The guys are working hard and trying hard and giving good energy and effort. That's just not good enough. The execution is not crisp. We struggled to score points when the game was on the line. Defensively, other than the first drive and the last drive, I thought we played pretty good," he said.
Del Rio also rejected any suggestion that the team quit.
"Show me examples of what would be an indication if you're going to keep bringing that up," he said of any suggestion the team has packed it in.
"You wouldn't say there was a lack of want to. That can't even be a sincere comment," he said.
"We're going to continue to do the right things for the right reason and look to execute better. I don't like to hear those questions (about whether the team quit)," he said.
"The guys that love to play the game, it will show," he said. "I don't think there is any question that Fred Taylor loves the game. I don't think there's any question that Maurice Drew loves the game. I think there are certain guys where it's real easy to see how much they love playing, competing. And, we must rally around those guys and keep working hard at executing together," he said.
But with four games left against teams still alive in the playoff race -- the Bears, Packers, Colts and Ravens -- the Jaguars might have trouble winning another game.
