Our non-Coastal opponents last year were Elon, Alabama A&M, BYU, UGA, Clemson, Syracuse
Duke's non-Coastal opponents last year were N Carolina Central, Memphis, Troy, Navy, NC State, Wake Forest
Do you think we'd have lost to any of those opponents on Duke's schedule? If the answer is no, or even if you're willing to consider that the answer is no, then we would have been 10-2 last year and in the ACCCG vs. Florida State.
If final record is truly all that matters we're perfectly capable of making a change to scheduling the Duke way. I doubt W's and L's are truly all that matters to you as you stated though. All schedules are not created equal. Consequently ACC opponents, or even just Coastal opponents, are a clearer way to compare apples to apples.
Now should CPJ include GT's 2008 or 2009 record as an indicator of his recruiting ability? That seems like a stretch and an oversimplification of cause and effect. To a point that's already been made, after removing those two years GT is still 4th in the ACC in W/L record during CPJ's tenure.
