5 NFL teams that will benefit the most from the emergency QB rule ft. Brock Purdy's 49ers

#3 - Miami Dolphins

Miami Dolphins QB Tua Tagovailoa

Tua Tagovailoa's health was arguably the biggest talking point across the NFL for a period last season. Tagovailoa suffered multiple head injuries and concussions, with some speculating that the 24-year-old should end his career early.

Both Tagovailoa and backup Teddy Bridgewater suffered concussions in 2022, meaning third-string rookie quarterback Skylar Thompson was sent into the game on multiple occasions. This included the Dolphins' narrow wild card playoff loss to the Buffalo Bills.

The new rule change will come as a welcome relief to a quarterback room that's struggled to stay healthy for a prolonged period.

#4 - Arizona Cardinals

Arizona Cardinals QB Kyler Murray

The Arizona Cardinals are without starting quarterback Kyler Murray for the start of the 2023 season, so the emergency quarterback rule will be music to their ears.

Murray tore his ACL last year, leaving Arizona with a host of backup quarterbacks including Colt McCoy and Jeff Driskel. The issue is that these quarterbacks haven't played substantial reps, so there's no guarantee their bodies can keep up with the NFL's grueling schedule.

#5 - San Francisco 49ers

The 49ers were the reason this rule was implemented, so they will definitely benefit from it in 2023. All of their quarterbacks in 2022 suffered injuries, namely Trey Lance, Jimmy Garoppolo, Brock Purdy, and Josh Johnson.

It's unlikely this unlucky streak will befit San Francisco again, but Lance, Purdy, and recruit Sam Darnold have had a history of injuries during their short NFL careers.
