Those unhappy with Cam re-signing are fans of Dink and Dunk offenses.

The Patriots re-signed Cam Newton. Some people are upset with it because of how bad of a passer he was in 2020 and blame him for the pass catchers going from 17th ranked to 22nd, while others blame Josh McDaniels for calling the same high accuracy timing route dink and dunk offense he ran for years with Brady.

I am one of those who hated watching Cam Newton in 2020. Newton looked slow making decisions on the option runs, he also looked slow as a runner. However, I didn't mind him as much as a runner because I thought that aspect was missing from the Patriots game offense under Brady.Where I had an issue with Cam is he is a mobile gunslinger. 

I grew up watching guys like Dave Kreig, Steve Walsh, Chad Pennington, and Joe Montana. In the modern era I have liked to watch guys like Colt McCoy, Trent Edwards, and Tyrod Taylor, while wanting the Patriots to draft guys like Mike White, Ryan Finley, and Seth Lobato to replace Brady.

These are "Dink and Dunk" quarterbacks. Guys who made their money of throwing passes of 10 yards or less, with a lot of them coming out of the backfield. They would manage the game eating up time on what essentially amounts to a three to five yard run. Relying on yards after the catch and waiting for the defense to come up and a guy to slip past them.

These guys run or ran a safe conservative offense where turnovers are kept to a minimum. Dink and dunk quarterbacks don't typically hit a lot of bombs or Hail Marys but as long as the offense is clicking, they typically can lead the team to a minimum of 3 points a drive. 

They also tend to eat up more clock, even on three and out plays drives, where as gun slingers are trying to get rid of the ball as quickly as possible to a guy sprinting 20-40 yards down field. Something that's helpful against teams with high powered offenses. Dink and dunk quarterbacks also tend to take less sacks because almost every target is a check down, unlike other offenses.

The NFL is a high scoring league, so anytime a team can avoid throwing interceptions or punting, it's beneficial. The average team has eight to ten possessions a game. If the quarterback can lead the team on at least one touchdown drive and three field goal drives, they can win as long as they eat up the clock and the defense plays well.
