Tom Brady and the New England Patriots continue to struggle heading into Sunday’s clash with the Cincinnati Bengals

Is it too soon to declare the window shut for one of the NFL’s signature teams?

For nearly 15 years, the New England Patriots have been held up as the example of what a successful franchise looks like. On Monday night against the Kansas City Chiefs, they looked like a team in disarray.

The offensive line couldn’t keep the pocket clean for Tom Brady, and he has few viable receivers to target. By the end of the game, Alex Smith looked like vintage Brady, and Brady looked like he was nearing the end.

There are personnel problems that are not conducive to the All-Pro quarterback finding success, but he’s also part of the problem. Brady does not appear to be playing with confidence and is making mistakes that he would have never committed in his prime.

Watch the New England offense, which is dependent on receivers running option routes, and you’ll see Brady is throwing after the receivers make their breaks, not before they cut in the direction where their route is supposed to end.

This is a problem and will not likely be cured unless Brady starts regaining or gaining trust in his receivers. Until this happens, it’s likely that New England will continue to struggle.

There almost certainly won’t be a change made this season, but the Patriots’ decision to draft quarterback Jimmy Garoppolo in the second round is looking smarter.

Underhill’s Top Five Teams in the NFL This Week

1. SEAHAWKS (2-1)

Robert Griffin III needs to thank Seattle for ending any talk about Kirk Cousins taking his job.

2. BRONCOS (2-1)

Our No. 2 team had the week off and will head to Arizona to try to drop the unbeaten Cardinals.

3. BENGALS (3-0)

Coming up against a struggling Patriots team this week. A statement could move them up a spot.

4. Cardinals (3-0)

Maybe it’s a mirage. But the Cardinals stay in the top five until someone exposes them.

5. Chargers (3-1)

Philip Rivers should be on the short list for the NFL’s MVP award and is the key to San Diego’s success.
