NASHVILLE, Tenn. -- Tennessee Titans defensive coordinator Jerry Gray and top defensive assistant Gregg Williams both have expiring contracts, but strong safety Bernard Pollard, who also will be a free agent, said only one of the two should return.

"Coach Williams was asked to come into a situation and be a voice, but at the same time it's not his ship to run; it's Coach Gray's ship," Pollard said after the Titans' 16-10 victory against the Texans on Sunday. "Coach Williams did a great job as far as making sure he could say some things but not step on toes at the same time.

"... I respect both guys. We don't know what's going to take place with anything. ... To be perfectly honest with you, Coach Williams, he's a D-coordinator. He's a lion. He is an alpha male. Guys like that, they want to be in their position. He knows and understands the situation that he came out of. He had to take a seat, he's humbled himself, he's learned, he's taught when he had a chance to.

"But he is a guy who wants to run his own defense. You've seen it before, he can run his own team. I don't see that continuing to happen, because you have to look at the things that go on. Coach Gray is the same way; he takes pride in what he is doing. They're both great guys, great coaches, they both will have a job."

Pollard laughed when asked which coach he'd vote for, saying it's not his decision to make.

It's unclear which direction coach Mike Munchak would go with a defensive coordinator. Munchak's fate must be determined first, and indications are it will be a deliberate process.

Munchak is expected to hold a typical season wrap-up news conference on Monday.

Munchak will meet with team president and CEO Tommy Smith this week, and indications are Smith will make a decision on Munchak's future by the end of the week.

Pollard said he talked with Smith before the game. He said Smith did most of the talking and was "encouraging."
