Kurt Warner: Did Rattler even have a chance against the Chargers?

I mean Warner had success in the Martz system which was vastly different than the Shanhan/Kubiak system. A major part of that is the QB has much less control and much less ability to change things up than in the Martz system. So, it's not surprising at all that Warner doesn't like it.

But I do think that the play calling for Rattler in the Chargers game was overly conservative and they didn't really set him up for success. The play calling for Haener dramatically changed and opened up. But maybe that's because Rattler wasn't ready for that stuff?

But, if Rattler wasn't ready for that stuff then why did they start him over Haener?
Apparently they’re seeing something in Rattler in practice a lot more than Haener, which makes them think that Rattler is the significantly better option to start for consecutive games. But what they’re seeing in Rattler in practice is falling apart in games. Rattler isn’t being properly prepared for pressure. Or real opposing defensive looks has Rattler falling apart in progressions. He looks like he’s overthinking throws which causes him to hold onto to the ball too long and take sacks.
