Time to give Haener a shot

Its unfair to ask a rookie QB to learn with this support group around him. When they announced Rattler as the starter, I figured it was because he could buy time with his legs. It's not working, he's getting killed. Not counting QB, we have Olave, Shaheed, Taysom, Ruiz and McCoy out. Now we're down some backups who were forced in to the startling lineup as well. It's just an impossible task.
I think people aren't giving Heaner enough credit for being a player who can move and run. Of course he isn't Lamar or Josh running ability. But I hardly see him take sacks in preseason. He has a quick release and scramble when needed. Rattler isn't as fast as I hope he would be. At this time I would not mind giving Haener a chance.
