New England Patriots receivers coach Todd Downing revealed the biggest lesson veteran wideout Stefon Diggs currently faces.

Patriots' head coach Mike Vrabel provided a cryptic response when asked why Stefon Diggs didn't play in Friday's preseason opener.

With the first half of training camp over, Diggs has fully established himself as a leader in New England’s receiver room. In the meantime, he put himself on that right path as well — both physically in regards to his recovery from major knee injury, and mentally as far as the acclimatization to Josh McDaniels’ offense is concerned.
