Maybe Rizzi felt the need to treat them like lil puppies that don't know better. Not saying that DA was a good HC but Rizzi is trying to shake things up, yeah it needs to be but as veteran a team as we are DA expected captains and team leaders to keep players in line as well.
The HC should not HAVE tell PROFESIONAL football players that they have to warm up
Yes, I expect my coach to tell my professional players to warm up. Just like during my entire football experience. I also expect my strength and conditioning coaches to tell my professional athletes how to improve their fitness... why? because they are professional football players!

AGAIN.... WHY would Rizzi make them mandatory... and the answer was to combat injuries. That is the literal answer to the question. Not a bunch of bull sheet about treating them like puppies.
