In regards to "just starting to read" McVay never gave Goff a chance to read. He held him in the huddle so long it was run the play as called even if it was a loser or get a penalty. How many times did we see Goff trying to change the play by his read only to get a penalty because McVay only gave him a few seconds to get the play off. Advantage defense because now they can simply tee off knowing he can't quick snap or draw them off sides.
Funny how people are amazed that Goff could develop in Detroit when they actually took the time to develop his skills and LA didn't. McVay didn't want Goff because he wasn't "his guy". But it's water under the bridge because now Goff can showcase himself and McVay got his "guy". LA got a Lombardi, Detroit got a franchise QB, both sides won IMO. Goff is professionally happy, and Matt is ecstatic because he got his ring before he retires.
The only real loss was losing Holmes. IMO the LA drafts have been good but Holmes is showing in Detroit he's a good judge of talent.
Goff had trouble with blitzes as a Ram (Miami game) and pressure (SF primarily) and that caused the majority of Goff's interceptions.
I blame that on Goff's inability to read a defense quickly to see the blitzes and being able to get rid of the ball quickly under pressure.
Now you may be right that Goff was rushed to the huddle too fast on those plays to be able to see those rushes coming.
I don't know to be honest.
But part of the growth of a QB is being able to read defenses faster.
As Jrry32 has stated many times, the best QBs usually don't start having their career years until their 6th season at the earliest.
Goff was just starting his 6th year when he went to a brand new offense without having any decent receivers until Amon St Brown started to come into his own and Detroit got Reynolds who is at best a number 3 receiver and he was number 1 at Detroit the first year.
So we will never know if Goff got better reading defenses his first year (6th overall) because of that reason.
However, his seventh year with better receivers definitely showed Goff's growth at reading defenses.
