(CBS) From his sideline hoodies to monotone press conferences, New England Patriots coach Bill Belichick has always hummed to his own tune in the NFL. He’s been remarkably successful in winning three Super Bowls, and to be frank, he doesn’t really care what others think.

So it shouldn’t come as a surprise that when the NFL’s coaches gathered for an annual league-wide photo at the owners’ meetings in Tampa, everyone was in it except Belichick, reports CBS Boston.

Here’s some visual proof.

From CBS Boston:

ESPNBoston.com’s Mike Reiss notes that Belichick is not a member of the coaches’ association (a personal choice of Belichick’s), which likely plays in to his decision to skip the photograph.

Still, you can’t help but think that Bill Belichick being Bill Belichick plays into this as well.
