I remember seeing the 1999 rams pre-season game with Green as QB...and there was a HUGE difference in the offense and confidence in the offense from the start. it was amazing. The play-calling was so aggressive, almost disdainful of any defense it faced
during the PS and of course into that year.
IF...I see some personality change on offense from this staff and new players, I would think the hints will start in PS.
Of course, it'll take many games to master consistency - even IF it looks good. We'll still get many ups & downs throughout the year until the lights go on and stay on for the players. I think even a vet QB like Ryan had a year of growing pains and I would think Goff would be at least THAT...maybe 2 years to get it 2nd nature.
That said, we can still win with a great defense and decent offense until then!
I hope. lol
