Similar circumstances but different as well, Goff was very young when he went to the SB and I don’t know how good McVay is at developing qbs. Stafford had been in the league a long time when he finally got there.
McVay did get schooled against Bill but there were a couple opportunities and Goff didn’t make the throws plain and simple. Stafford saved the rams bacon several times in the SB run, he’s got a “don’t worry I got this,” swag and they rode it all the way to the title. Goff is more the silent assassin, never giving away what he’s thinking.
McVay didn’t have the kind of bromance with Goff that he has with Stafford and I think he was scapegoated, but he wasn’t great the year after the SB. Sometimes 2 good people aren’t good together.
