For the past three years, it’s been incredibly obvious which player opposing teams key on when facing the Rams. He wears No. 30 and goes by the name of Todd Gurley.

Since he came into the league, Gurley has been the Rams’ best offensive player, and one of the top running backs in the game. His role has changed a bit this season, and the offense isn’t as reliant on him as it was the past two years, but there’s no doubting he’s the man that makes the offense go.

The Giants, whom the Rams face on Sunday, are well aware of Gurley’s ability to take over a game. Landon Collins said this week that in order for New York to have a chance, it has to stop No. 30.

“They’re fast and explosive,” Collins said of the Rams’ offense. “They definitely rely on Gurley and that’s big. We definitely have to stop him and if we stop him, we have a chance.”

Collins, who plays close to the line of scrimmage, will have several opportunities to bring down Curley in the open field. That doesn’t mean It’ll be easy for him to do just that, but Gurley gets to the second and third levels often, which is where Collins roams.

Olivier Vernon may not play on Sunday due to an ankle injury, but like Collins, he realizes just how important it is to shut down Gurley before he gets going. If not, the Giants have almost no chance to beat the Rams.

“They have a great running game. Gurley, he’s been having a great year and one thing we have to do is just stop the run,” Vernon said. “We can’t stop the run, then it’s going to be a long day for us. So we know the jobs we have to do as far as our unit to help us get this W.”

The Giants have struggled against the run this season, ranking 20th in yards allowed (845). One area where they’ve stood tall is in the red zone, allowing just two rushing touchdowns all season.

Gurley has five touchdowns on the ground this season, and if the Rams’ offensive line plays well, he’s likely to find No. 6 on Sunday.
