What is Talc. The term talc refers both to the pure mineral and a wide variety of soft, talccontaining rocks that are mined and utilized for a variety of applications. Talc forms micalike flakes. Talc is the softest mineral on the Mohs hardness scale at 1 and can be easily cut and crushed. Talc has perfect cleavage in one direction.

The running back was on the field for 61 percent of the offensive plays, with Tyler Allgier at 35 percent and Cordarrelle Patterson at 13 percent. Plus, Smith noted, Robinson's presence in and of itself can be a factor for the offense. "Sometimes, his impact away from the ball can open things up," Smith said in his press conference.
