You are wasting way too much text on this.  There are two solutions to your LT failing as a pass blocker - as long as the rest of the o-line is still performing OK.  You either run (draw or trap, both work) or you have your QB roll right at the snap.  As long as your run game is still performing, and your QB has good legs (ours does), and the right side of your line is pass-blocking well, you'll be OK.  The QB just has to be aware of the possibility of a blitz from the right and have a plan to throw it to the receiver left uncovered by the blitz.

 

If Sam Young starts against the Dolphins, we will see plenty of this.
