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.

Stamp mills use a vertical crushing mechanism to break down ores, via a set of battery pads. The number of crushing pads varies between models, and those with more pads will generally come with a greater crushing capacity. Stamp mills are less sophisticated than ball mills, but affordable and effective for basic rock crushing.
