FOXBOROUGH, Mass. -- Tuesday is usually the day that NFL coaches make a deep dive into formulating their game plan, but with Super Bowl LII not being played until Feb. 4, the day has been a little different for Bill Belichick and his New England Patriots staff.

It's basically "Get to Know the Philadelphia Eagles Day."

Belichick called Tuesday "a major working day" that is also "kind of a catch-up day for us because we just don't know very much about Philadelphia."

That makes it a similar situation to last year's Super Bowl against the Atlanta Falcons, but different from others in which the team has played under Belichick.

"Other years when we had played a team more recently like Seattle, who we had played two years before but in a regular-season game, there was some carryover from that or in the [New York] Giants years where we had played those teams in the regular season, there was a little bit less of an acclimation to the opponent because we had some background with them," Belichick said.

There is no such background with the Eagles under second-year head coach Doug Pederson.

"We have a lot of ground that we need to cover, so we're at it hard trying to catch up so when we bring the players in we'll be ready for them and we can do a good job of presenting the information to them efficiently and accurately because, again, there's a lot of information to digest," Belichick said.

"There's 16 regular-season games, and then there's playoff games, and then maybe some additional other things that get kind of get tossed in there as well. But the bottom line is it's a lot to sort out and then pull together pretty concisely."

The coaching staff is casting a wide net.

"For all those games that we look at -- let's call it 18 games, just to pick a number -- that's probably 2,500 plays in all three phases of the game and there's just going to be 160 [in the Super Bowl]," Belichick said. "So they can't do everything that we've ever seen them do any more than we could run everything that we have experience running, so we have to whittle down our side of it.

"We know that they're going to have to only be able to run so many plays, and so the idea is, we have to be prepared for a lot of things. But at the same time, we can't be overly distracted by things that either have a low percentage chance of coming up or probably wouldn't be the type of thing they would do against us. We try to eliminate some of those and make sure we work on the things that we feel are most problematic or may be most likely to occur."

In doing so, Belichick said the Patriots are already behind their regular pace.

"Our pro scouting department has done a good job of advance scouting, but from a coaching standpoint, the coaches haven't really been focused on this game," he said. "We were focused on Jacksonville and now we turn our attention here to Philadelphia and there's a lot of work to do. They're obviously a great team and they're strong in every area. That's why they're playing in this game. Our attention is on them, but there's a lot of work to do."
