ALLEN PARK -- The first few moments of Matt Patricia's first open practice with the Lions featured some new tests of will.
On one end of the field, running backs lined up with the ball behind three bags made to simulate offensive linemen. When the back would approach the line, assistant coaches would fill two of the holes to force the runner to make the right decision and go.
On the other end, later in the practice, backs took handoffs and ran toward a speeding linebacker before making a cut to avoid an open-field tackle.
The goal of the day was to simulate moments that should come in a game.
