Mike Singletary coaches like he played: all-out. No hesitation. React quickly, decisively, instinctively. Good for a linebacker. Not so good for an NFL head coach. Singletary over-reacted (like the referee) when he gave his TE Davis the boot last Sunday for an unsportsmanlike-conduct penalty in the 49er's game against the Seahawks.
The coach is sending a message to his players and the organization that selfish play will not be tolerated. Good message. But taken as a whole, Davis' behavior appeared more defensive than selfish by reacting to loudmouth taunts. Not the wisest behavior but hardly anti-team. This is not some prima donna getting in the face of his coach because he's not getting the ball enough. Mr. Intensity as a player, Coach Singletary should know better than anyone how football players are wound-up tight and prone to pushing back.
Fortunately for the 49ers, Davis seems to have taken the embarrassing ejection in stride. As for Singletary, it's still early. He could be the next Bill Cowher or the next Les Steckel (ex-marine who succeeded the legendary Bud Grant by (mis-)guiding the Vikings to a 1-15 (?) record in the early 1980s).
