Yes. To the bolded. That's all I'm trying to say.
I'm not saying he hasn't been accurate. I'm not saying he doesn't throw accurate passes. I'm not saying his incompletions weren't mostly decent passes. I'm not saying anything other that he doesn't have to throw the ball away much, which directly correlates to a higher completion percentage. His completion percentage isn't bogged down by incompletions due to throwaways. Because he's mobile, he doesn't have to throw the ball away. When he's under pressure, he either throws a very, very accurate ball or scrambles, which means he doesn't have to throw the ball away, which helps his completion percentage. If a play breaks down, he can scramble and find an open receiver to complete a pass, rather than having to throw the ball away, which helps his completion percentage. Because he's mobile. Which helps his completion percentage. Because he doesn't have to throw the ball away much. Because when there's pressure, he can either carry the ball or scramble to find an open receiver to complete a pass. These passes are sometimes deep, and he does a good job completing them. Because he can move away from pressure, rather than having to throw the ball away. Which helps his completion percentage. etc. etc. to infinity.
