No way of knowing.
Playing vs 4th and 5th stringers is not a true test. He has measurables for sure.
Playing on Sunday vs a startin defense that has had time to get a book on him and prepare to face him....totally different thing.
Keenum is the best player at the position now probably by a decent margin. He had shown the ability to be solid on Sunday, to read a D to get the ball out on time ect.
I'm not saying Mannion should start even though I'd like to see him get a shot. But saying he was playing against the 4s and 5s as early as he came in? I'm doubting that. I don't know Dallas' roster but by all accounts, the 2s should have still been in the game when Mannion came in. Goff was scheduled to still be playing from what we were told and likely the only thing stopping that was Marinelli being a dick and dialing up blitzes as soon as our Rookie trots onto the field.
All that being said, I have to say that I thought Mannion simply looked better in virtually all regards than did Case. Was it because of the level of defenders? Maybe. But what I was looking at wasn't about the defenders as much as it was about Mannion's stance in the pocket, his delivery, his timing, etc. He missed badly on a couple throws. Got it. So did Case and so did Goff. If you want to boil anything down to the first game of the pre-season, that would be a big one. These guys (all of them) are going to miss throws.
Why do people make post like this? It was one preseason game.
Because they feel like it and it generates discussion. 47 responses so far. Not bad.
I can see why some would think it insane to think Mannion is an option at this point and one pre-season game shouldn't change that. Others, however, see potential in the Pacific Division's all time leading passer. You don't oops your way to that distinction - especially in Riley's offense.
Add to that the game he showed and Fisher's comments after the game..... how can you help but wonder?
