Give him a break. It happens to every QB. Maybe he'd be a bit more patient if the line had been protecting him better in past games.
LT is the first read, Sanchez had him open, so he threw him the ball. If the first read was keller, he would have gotten the ball. If LT wasnt there, Sanchez would have seen Keller, because he would have looked for him. It was a good play call, because they got LT against a linebacker, thats a matchup the offense will take every day, and twice on sunday (or monday as it happens) as it was mentioned, if LT is able to get his hands on it, he probably scores by outrunning the LB
The Dolphins are going to clean house if they finish with the first pick so I'm sure the players and coaches could give a crap about Luck.
