This would be true, if it wasn't completely false.
Most teams use their best pass rusher on the left side of the d-line to take advantage of the (generally) lesser skill set of the right tackle.
Moving the ends around is also a trend that's been picking up steam recently.
So, no, the left tackle generally doesn't face the best pass rusher all game long.
I'd like to amend my own post. I shouldn't say "most" teams, since I don't have the numbers in front of me.
I will say that a lot of teams are trending towards using their best pass rusher(s) all over the place to take advantage of better match-ups. This is especially true in 3-4 alignments.
