"It’s looking at what other people are seeing from you," Belichick said. "I think every good team has tendencies. ... You look at it and say, ‘There they go again, there’s that same play happening again.’ So I don’t think those tendencies are necessarily a bad thing, but there’s a point where you want to have balance, and do things that complement them."
2) Production: This can be interpreted as judging players. Or judging play-calling. Or getting a better idea of where you're good and bad as an overall group. And yes, situational football plays into this one, too.
"What plays, how productive are they in certain situations," Belichick said. "If that play’s productive on first down, how productive is it on third down? Right side, left side, man coverage, zone coverage, all those things. ... To a certain extent, there may be things you want to build on, there may be things you want to subtract. So if you spend too much time getting out of it, maybe you have to refocus on something that’s more productive."
And then there's assessing that production in context. Which is to say, for example here, that maybe you throw out what happened when you were leading Tennessee 52-0 in the third quarter two weeks ago.
“You’ve got to be careful," Belichick said. "Yeah, these plays were good, but they obviously didn’t really matter one way or the other, offensively or defensively. Some of those plays were kind of throwaway plays. And some of it was a factor of the weather, too.
"I think in some games, some of the plays that happened in that game, put them on a different field and I don’t know if they would have turned out the same way. Both ways. Chris Johnson’s long run, I don’t know if it’s a good field we miss that many tackles."
OK, so how do coaches take all of everything that's happened into account. Coaching software has made it much easier. You can filter through almost anything imaginable efficiently now.
And during the bye week, all that stuff sure gets a workout.
