It's possible Steelers offensive line coach Mike Munchak just had some time to kill Tuesday morning.
More than likely, he stopped by the University of Pittsburgh's Pro Day to get another look at offensive line prospect T.J. Clemmings, one of the more appealing commodities in the 2015 NFL Draft.
Clemmings has excellent athleticism and a great frame for an NFL offensive lineman - likely at the tackle position. His lack of polish is something of a concern, and most talent scouts see him as a project with an excellent amount of upside.
The Steelers are in a tough spot in terms of finding top-flight pass-rush help with the 22nd overall pick. It would seem the top six eligible edge rushing players may be gone by the time they go on the clock. That will leave them with intriguing options, like the project that is Clemmings.
He did not run Tuesday, and did not appear to be up to the same level as other prospects participating in the Senior Bowl, but that rare combination of athleticism and size is intriguing. Players like him do not often fall far in the draft, and many have him being selected in the first round.
Several Steelers coaches were on hand, including defensive backs coach Carnell Lake. He could have been taking a look at safety Ray Vinopal, who reportedly had a good workout.
