To anyone that coaches or played o line…

I agree that rotating OL like defensive linemen do is not a good idea. In order to function well and execute as a complete unit, like all 5 digits on the hand, the continuity and unity developed from hundreds and thousands of repetitions next to each other are essential. I can tell you from experience that knowing exactly how the player next to you moves, knowing his timing on pulls, double teams, traps, etc. is vital to well orchestrated execution.
