Be warned: Robert Quinn believes he can improve Posted Jul 30, 2014 Forget for a moment the freakish athleticism. Put aside the elite speed. Don't acknowledge the explosive ability to transition from quickness to power. All of those things combine to form the pass rushing terror that is St. Louis Rams defensive end Robert Quinn. Now consider Quinn just turned 24 in May and members of his coaching staff still believe him to be something of a pass rushing neophyte. (ESPN.com)
