The problem with this thread is that the OP has framed the "Primary Issue" completely wrong. The offense is not the primary issue. That's like saying the primary issue for losing weight is what kind of diet I choose, Keto, Adkins, Paleo etc. No it's not. The primary issue with losing weight is do you have a relatively balanced diet, disciplined portion control and regular exercise.
The biggest variable in college, high school and youth sports success is relative talent level. It's no coincidence that the top teams every year consistently have the top ranked recruiting classes. Is Matt Painter's offensive system better than RU's or do they have have better players? Is Ryan Day better than Schiano at X's and O's or does he have a stable of NFL talent to work with? Show me a successful college coach and I'll show you the consistent level of pro and high level college talent they have. Good players make good teams not good plays.
If we have a core of 2-3 star talent, the middle of the league has 3-4 star talent and the top of the league 4-5 star talent, where would you except us to be? The fact we've been able to get to the middle of the pack and flirt with the top half is a testament to our coaching and player development. Building a program is not a straight line, it grows like the stock market. You'll have periodic pullbacks within a longer term uptrend. Our recruiting the last few years was better than Pike's first few years and our future recruiting even better!
In his third and fourth year Chris Collins won over 20 games and and got Northwestern in the NCAA tournament for the first time. A few years later he won only 8 and 9 games. I wonder how many posters and media were questioning his coaching, his offense and whether he was the right guy? Fast forward to last year and another 20 plus win season and NCAA bid. This year he's on the doorstep of another 20 win season and NCAA bid.
Next year we have one of the top recruiting classes. Really amazing considering where this program was prior to Pikiell. We all want instant results but consider the mountain we had to climb and remember lasting growth, like the stock market, is not in a straight line.
