I'm not weighing in on either side of the rumors. The fact that all of this did roil up has had to have some impact on the internal dynamics between Butch and the players. I wonder if a player or group of players flatly told him that booming over a microphone during practice had become impossibly irritating. (I seriously doubt Cheek's investigation addressed this.) If player input is the reason Butch went unplugged, it is highly likely they gave additional input on other simmering issues that had become deeply bothersome to them. This would mean, for better or for worse, that Butch could be in the process of adjusting some aspects of his coaching style. If true, I suspect it will positively impact team morale.
BTW, I wondered about the wisdom of the microphone the first time I saw a practice clip with it being used. I knew if I were a player that it would very soon get on my nerves to the point of supreme distraction. A leader, on or off the football field, must constantly ask whether the techniques and tactics used in order to lead are serving as sources of pressure or sources of motivation. We all enjoy being motivated; nobody can long endure pressure without very negative ramifications.
So, if the microphone has been put on mothballs, I see that as a positive thing and hopefully a sign of better things to come for this team.
