The biggest concern I have about Davis at this point, is he just doesn't seem to see the field, and holds on to the ball way too long. Then, his "instinct" is to just pull it down and try to run. He does this is training camp way more than he should, including on some of the 7 on 7 drills.
Clemens tends to hold the ball as well, but when he "runs" it is usually to keep the play alive and more than not, finds a place to throw the ball. Case in point, the TD to Radway. He also realizes when he needs to just stand in there (dropped pass by Radway) based on the game situation.
I think Austin Davis also is showing signs of having accuracy issues. Not sure if this is a by product of not being comfortable in his reads yet, or if he truly is just not throwing the ball well, enough. There were throws last night that were indicative of this.
I realize its ONE PRESEASON GAME, but I'm not ready to hand the #2 job over to Davis yet. Not from what I have seen everyday in camp, and especially after seeing last night's performance.
