what distinguishes the difference between RT and LT?
RT the strong side more run blocking?
LT pass blocking?
These are the things I would like to go over in play studies.
This is a caveat to what TexasTideFan wrote.... It also depends on whether your QB is left or right handed. The best pass blocker has to play to the QB's blind side (which is the opposite of which hand he throws the ball with).
