Maybe you should take the RU DB job.
Over the last few years we have put together some really good DB stuff to get our kids in the right position. I knew we were doing a good job with what we run because our entire league was talking about the "man coverage" we run and we do not run man coverage ever.
We run a pattern read system. Essentially never covering empty space. Helped us force 19 turnovers and 66 TFLs this season. 1 of my CBs is shaping up to be a D1 kid with the potential of a sophomore CB to get there also.
