don't read too much into that, those kinda critsm is more based on losing than it be a bad idea.....want to bet if there was a story about Belicheck working with the scout team the tone would be, "that's what makes him a great coach no detail too small, cares about making sure all 53 player are developing, etc." But because itis a losing coach it is wrong priorities
But it is the
wrong priority when your starters aren't getting the job done, and your team looks like cow pies in the field. For any coach of a team that is playing well it is okay to work with the scout teams.
