Is Texans' Sam Montgomery out of shape?

Texans third-round rookie outside linebacker Sam Montgomery was placed on the team's non-football injury list Monday.

Indications are it's not an injury that landed him there, but his conditioning. (Texans' brass, ridiculously, has declined to confirm anything, treating it like a state secret that makes it a bigger deal than it needs to be.)

Texans rookies reported to training camp Monday and Montgomery apparently didn't show up at neither the weight nor in the condition the team expected.

That's not necessarily a giant issue, but if it's the case it is a disappointing development given the questions Montgomery carried into the draft in late April.

The strength coach at LSU, Tommy Moffit, included Montgomery on a list of players he wouldn't talk to NFL scouts about because they "miss workouts and always have an excuse."

“They lack the self-discipline and motivation to take care of their responsibilities,” read a sign from Moffit on an office door in the Tigers' facility. “I will not answer questions regarding their performance numbers or character, as they care only about themselves.”

I discussed that and Montgomery's poor interviews at the scouting combine in this column on the day the Texans drafted him.

Montgomery was initially slated to compete for time at strongside linebacker along with fourth-round pick Trevardo Williams.

But Williams told me in June that Montgomery was working on the weak side, where 2012 first-rounder Whitney Mercilus will be the starter.

We don't know how much progress Montgomery must make to get off the list and into action. But the first practice with the entire team is Friday morning.

If he misses that, the concern level goes up at least a notch.
