The Rams responded to Goff losing the Super Bowl by giving up a 1st round pick to get rid of him.
After the Rams lost the SB with Goff, they responded by giving him a record setting extension. Your statement was full of shit. Now eat it. Two years later the Rams traded Goff, with McVay admitting he could have done better with Goff. It is not a matter of if you think Goff is "elite" or not, the fact remains he was an added value to the Lions, and it's stupid to suggest otherwise. So yes, Goff had a bad game in ONE SB. It happens. Yet, he has not been Kirk Cousins bad on the big stage either.
To date, JF has been nothing but a bottom of the barrel passer, that can run with the ball. I used to hear the same shit over and over about Stafford, how he could never win a SB. How did that work out for you? Coming from a franchise that trotted out Andy Dalton, Mitch Trubisky, and Mike Glennon, I find Bears fans criticisms of Goff highly entertaining.
