I think its pretty clear you aren't educated on OL play so I'd stop here. Technique and scheme are very different. College OL are rough around the edges in technique because they play in spread offenses. This is very much still a spread offense. We aren't changing technique as much as we are gap assignment. When you have teams moving around the LOS and LBs walked up from gap to gap it's difficult to determine whose coming and whose not. Especially in a new offense or scheme, but not technique.
The "power" runs simply mean guards are pulling vs zone blocking. I prefer zone blocking, but the issues we are having are still mental rather than schematic. When you have an OG and an OC doubling the NT and letting the only LB that can make a play run free, that's a execution error not a schematic error.
