Boras' offense was already regressing at the end of the season, especially at the QB position. Only some of that was on Keenum. A fair amount of that was scheme.
This offense can simply NOT play from behind. If the offense or defense gives up points, it's basically game over. This offense that they will run with Keenum or Mannion or Goff does not feature many routes where the QB can hit the receiver in stride to allow for YAC. As you'll recall, any time a Rams receiver got YAC, it was a surprise...a genuine surprise. "he caught it...AND HE'S STILL RUNNING?!!! GO!!! GO!!!"
With a year of film of how the Rams intend to block for Gurley, his speed won't be a surprise (I truly think he caught teams off guard with his burst). Teams are going to stack the box and force the Rams to beat them through the air. Boras has a few misdirection counters like Tavon on the reverse, etc, but those aren't staple plays. We had a few successful screen passes, but in general, it's still a cringeworthy play that loses yards for the Rams. With the 3rd toughest schedule in the NFL this year, we're going to have to give teams a reason to respect the pass.
How'd we do with Boras' pass offense that Fisher and Snead think Goff is perfect for? Near historically bad in the modern era. What was it, 145 yds per game?
I'm glad Cook is gone, but he was our best seam threat. It got so bad that over that last few weeks, we KNEW anything more than 3rd and 6 wasn't going to happen. And I realize that Case Keenum isn't star-spangled awesome, but he can execute a well designed play and throw the ball 10 yards downfield. He's a competent QB. Which begs the question, how, no matter who's the QB going back 4 years, can this team still not have a QB throw the ball past the 1st down marker?
Either, every single QB doesn't understand how to make a first down or the scheme absolutely STINKS ON ICE at accomplishing the Fisher's main goal after scoring points, which is to chew up clock, get 1st downs and convert 3rd downs. It's a combination of playcalling, scheme and personnel.
They're not changing the Offense. They BELIEVE in it. They believe they won with it (I am fairly certain they won in spite of it). They BELIEVE that it's tenable long term. I'm fairly certain that defenses have proven to adapt much faster than offenses unless they have unique elements. This Rams offense has no unique elements. And while Gurley ran for hundreds of yards in consecutive games, he also got held to around 50 a fair number of times. Without Gurley breaking long runs, the offense stalls, the box is stacked and Johnny Hekker gets the Jimmy Leg from punting every few minutes.
Fisher and Snead have drafted well... if they were going to try and emulate Pittsburgh which for being a smashmouth running team has a dynamic passing game now that the QB knows it inside out and has years in the system. Earhardt Perkins systems are like that.
But they aren't going to do that. They are going to keep trying to fit a square peg in a round hole. They're going to keep trying to run this quasi-WCO with other elements duct-taped on with miscast personnel and a scheme that doesn't take advantage of the box stacking that happens with Gurley in the backfield.
Defense and Special Teams have really kept this team in games they had no business being in. I can't recall the last game the Offense just...won. And because of the commitment to the Boras offense, there's little chance that happens in the future.
