ESPN analyst Joe Theismann answers five key questions after NFL Week 5:

Is it too early in the season to call the Monday-night game a "must-win" for the Bears?
Yes, it's too early to say that. There's plenty of football to be played, and it's only Chicago's fifth game of the season. Every team wants to get on a run at some point, but at this stage of the season there really isn't a must-win game. Now, you could say the Rams' next game is a must-win -- mainly for self-respect.

This is an important game for the Chicago Bears, though. If they beat the Green Bay Packers on Monday night, they'll be tied for first in the NFC North (the Bears enter the game at 2-2, the Packers are 3-1). Anytime you play a division rival like Green Bay, it gets the juices flowing.

So this is an important early game for the Bears, but not a must-win. But at the end of the season when the playoffs are on the line ... well, those are the must-win games.

	Brady

Are the Patriots' problems mostly defensive or do they also have some offensive issues to address?
The Patriots' problems are mostly defensive. Mainly, they've been susceptible to the run. Two weeks ago they were gashed by Priest Holmes and the Chiefs, and last week LaDainian Tomlinson and the Chargers had a field day. This week, Ricky Williams had 105 yards on 36 carries in the Dolphins' 26-13 win.

Those are three of the better running backs in the NFL, but still it's clear that New England needs to do a better job of stopping the run. That's got to be the No. 1 priority. The Pats must use their multiple defensive looks to their advantage, which they haven't done consistently yet.

Offensively, the Pats are making too many mistakes (Tom Brady threw two picks Sunday). So they have to protect the ball better.

Is Ramsey the permanent solution to the Redskins' QB problems?
Time will tell if Patrick Ramsey is the long-term solution, but coach Steve Spurrier has to start his rookie QB now. Spurrier has gone back and forth between Shane Matthews and Danny Wuerffel. But Sunday against the Titans, Ramsey showed he's capable of leading the Redskins. So I would stay with him.

I believe Ramsey is the best QB the Redskins have, and I also believe that the Fun 'n' Gun suits him well. He has a nice touch and he's tough. Ramsey has a good grasp of what Spurrier wants to do on offense.

Were the Redskins that good offensively on Sunday or were the Titans that bad? Only time will tell. But Washington put up some points -- 31, to be exact -- and you need to stay with the guy who's getting it done.

Any surprise at the early success of Callahan, Dungy and Gruden in their new posts?
Not at all.

Raiders coach Bill Callahan was an excellent coordinator under Gruden, and now he's putting his stamp on the Raiders. One difference in this year's Raiders is that they're running the ball more effectively. And a subtle reason is the return from injury (torn ACL) of center Barret Robbins. Having him back has made a world of difference in both pass protection and run-blocking.

Meanwhile, Colts coach Tony Dungy (the previous Bucs' coach) and current Bucs coach Jon Gruden took their previous teams to the playoffs. So you'd expect them to have similar success with their new teams.

Both the Colts and the Bucs will continue to improve as they become more familiar and comfortable with their coaches' new systems. They'll get better as the season progresses. The Bucs are beginning to understand their roles in Gruden's offense -- Keyshawn Johnson posted a big game Sunday (six catches for 131 yards). And Dungy has the Colts' defense playing tougher and preventing the big play.

So how do you think the ugly AFC North is going to shake out?
For those who are still trying to figure out realignment, the new-in-2002 AFC North is made up of the Cleveland Browns, Baltimore Ravens, Pittsburgh Steelers and Cincinnati Bengals.

	Lewis

The Steelers (1-3) have to be thankful that nobody is running away in the division. The Ravens started 0-2 but are now 2-2 after defeating the Browns (2-3) on Sunday Night Football -- good enough for first place. Baltimore is gaining confidence, while the Browns still haven't found it yet. The Ravens are young and improving, but they're susceptible to injuries to their stars. What happens if Ray Lewis, who was forced to leave Sunday night's game with an injured left shoulder, can't play for a couple of weeks?

Ugly is a good adjective for this division. But we've got to remember, a frog became a prince ... which makes you wonder who will become the prince from this group. A 9-7 record is almost a lock to win this division -- heck, maybe 8-8 will win it.

Cincinnati is the X-factor in the AFC North. If the winless Bengals pull some surprises, they could screw up the postseason hopes of a division team or two.

With the new divisions this season, it's so important to win your division. With four division winners and just two wild cards -- rather than the old format of three and three -- a 10-6 team from the tough AFC West could miss the playoffs while the AFC North winner gets in at 9-7.
