It would be sending the message that poor play will not be tolerated.
Some talk as if Sunday was Mckenzie’s first mistake. It’s not. He routinely muffs punt/kick returns. He usually gets it back, and it’s not counted as a fumble because statisticians don’t consider muffs to be fumbles as the player did not securely gain possession, but it happens much too often.
I realize that it’s a faux pas on this forum, but sending a stern message is one thing we could stand to learn from Belichick. His dog house is real, and he keeps players in there for a lengthy period of time.
