Was the Skins game, where Jay Gruden had a gameplan ready with answers for what his offense wanted to do (which was basically Gruden's offense with more emphasis on the wideouts vice TEs). I think that one was a big time learning evolution for Sean, and this time around he's going to be prepared to flip the script.
My main concern is the Rams stopping the run. Lynch looked really good in his limited preseason snaps. I think Gruden's going to mash it and try to shorten the game and keep Goff & company off the field. Hopefully the Rams' defense stuffs it early and often and puts them in third and forever all day long.
