It is not in Takkarist McKinley’s nature to sit out of any football activity, so he said it was “very frustrating” to watch the first day of the Atlanta Falcons rookie minicamp from the sideline. McKinley, the defensive end from UCLA who was the Falcons’ first-round pick in last month’s draft, had surgery in March to repair a torn labrum in his right shoulder. This was after playing with the injury for two years and completing 24 reps on the bench press at the NFL draft combine.
