Not really unexpected, rumors were that Garrett held Moore back with a desire, or wish or direction to have conservative play calling. To think MM would come in here, with one limited off season, with no preseason and transform the offense to the SB-winning Rams offense is unrealistic.
Look at it this way - what if Moore didn't get to run the plays the way he wanted under Garrett, why wouldn't McCarthy sit back and watch what Moore does "unfettered"? It might be one of the best offenses ever seen, remember he didn't get to see Moore call any preseason games, discussions, etc. can only tell you so much.
Well now he's seen "Moore's offense", and it wasn't very good, very imaginative or very different that what he saw in 2019. Is one game enough for MM to "take over" the offense?
We don't know, maybe even MM doesn't know. He might wait another game and take it over, might have a review of game film and make slight changes, or any of another number of scenarios.
It is a long season, since the only really supposed contender for the division title, the Iggles, lost as well, and the Giants also lost this loss isn't a big deal as far as the whole season goes.
Now am I optimistic as to the rest of the season? Not on your life, and that's not even considering that we lost 3 starters in the game, all for at least a few weeks, and I suspect more like half the season for two of them.
Just saying while it looked like more of the same, like the last few years, it won't necessarily be that way for the rest of the season. Doesn't change my attitude, it's still "show me"/"wait and see", not optimism, not pessimism, no real feelings one way or the other...
