If you listen to Mora's comments to the media, he has praised all the QBs. To me, it sounds like he wants to keep the competition going so they will all be motivated and sharp. If he has a favorite, he hasn't really made a public comment yet. It may be different behind the scenes.
The press has been useless. The thing they should be looking for is how fast the QB is making decisions and getting rid of the ball. How fast are they going through their progressions. How clean is their footwork. Do they look in rhythm. Command in the huddle. All they talk about is this QB threw a completion to that WR. Useless.
