NASHVILLE, Tenn. -- As the clock ticks toward Saturday’s opening practice of camp for the Tennessee Titans, the roster stands at 89.

Will they use the 90th spot to sign veteran receiver Andre Johnson, who was one of several players who visited the team Tuesday?

That remains unclear, and a source said nothing is pending.

While he’s 35, Johnson's super-productive career and his reputation as a consummate pro and worker make him a big subject of conversation until the Titans fill the spot.

I spoke to four personnel executives with other teams and asked them if they thought Johnson was worth a look for the Titans.

“Nah,” said one.

“He’s at the end,” said a second.

But two others had a different view.

“I’m sure he has some value," a third personnel executive said. “I could see them using him in a mentorship role for their young guys. I’m not sure if that is his mindset, though.”

"He’s big as hell, and I think still has some juice to produce in a reduced role,” the fourth said.

At the top, the Titans' current crop of receivers is composed of Kendall Wright, Rishard Matthews, Dorial Green-Beckham, Tajae Sharpe, Harry Douglas and Justin Hunter.

Douglas qualifies as the veteran leader of the bunch, but he’s never played at Johnson's level and isn’t guaranteed a role or even a roster spot. Johnson wouldn’t be, either.

As I said here, I’m not big on guys being signed primarily as mentors.

When the roster gets to 53, guys have to be on it because they can play.

While they have 37 extra players, a guy with Johnson’s resume might well rate worth some time on the roster while the Titans assess not just him, but everyone else.
