The OP is illogical in that he states that the new OL could not hold up under the long developing plays that Richt called. Richt is no longer with the team and there is no basis for asserting that as a risk with the new playbook an unknown. Also, if you pay close attention, the tensile strength of a paper bag changes when wet. Try tearing a wet bag versus a dry one. It bends more and takes more effort to break. Also, a line, like paper, can be trained to produce wet paper strength.
This is a good attribute for an offensive line.
