The Chicago Bears have been rotating Teven Jenkins and Lucas Patrick at right guard for the past two weeks, and it's been pretty much an equal split of repetition.
The rotation is happening as Patrick recovers from a broken right thumb suffered early in training camp. Patrick was brought in to be the starting center, but he's been unable to snap the ball through the first two weeks of practice. As a result, they've been keeping him in the mix at right guard.
However, for the first time in months, we have actual video evidence of Lucas Patrick snapping a football!
