Will P90X be sufficient for my son's off season football strength workouts? My son is 14 to be 15 in Dec, he plays football for team that regularly makes the state playoffs. I am implying that the team has a normal off-season weight/speed/agility training program

He has expressed a strong interest in using P90X with the goal of bulking up.  He is 6' feet and 185.  Lean and long limbed body type.  He has the room to pack on some muscle. His frame will eventually fill out to 240-250 if he continues to add height.
