The New England Patriots are preparing to face a Buffalo Bills team that is also undefeated this weekend. Ahead of Sunday's matchup, Bill Belichick says that Josh Allen brings “another dimension” to the Bills' offense.

“He’s like a running back,” Belichick told reporters Wednesday morning. “He breaks tackles. He’s got good speed, good power, and he’s shifty. He avoids and breaks a lot of tackles. It’s another dimension, sixth receiver in the passing game if you will. Gives them another blocker in the running game when they have designed run plays for him.”

Since his rookie season in 2018, Allen has showcased his ability to extend or create plays with his legs. At 6-foot-5, nearly 240 pounds, Allen is not an easy quarterback to bring down to the ground.

Through three weeks, the second-year quarterback already has 105 rushing yards and two touchdowns. Along with that, he also has two broken tackles as a rusher; which is as many as he had in 2018.

Among all of the undefeated teams remaining in the NFL, the one team who continues to get overlooked is the Bills. Buffalo has vastly improved on both sides of the ball and Allen is showing signs of improvement as a passer.

When Allen came into the NFL, some likened him to Cam Newton of the Carolina Panthers. Both quarterbacks are of similar builds, but Newton was slightly more dangerous running the ball earlier in his career.

In Week 4, the Bills franchise quarterback will face his toughest test of the season in the Patriots defense. At the same time, New England's defense will have their hands full slowing down Allen.
