If the coaches have a good eye for talent, which I think that they do, I believe the long game and full defensive install is the way to go. No doubt, watching the LB's try and cover this year is brutal. We are nowhere close now. It is a drastically different defense, but you only learn it by playing it. IMO, if a CU turnaround is what you want the only way CU can contend for the PAC12 South every year is to install and recruit to this defense. I believe Tucker and staff can do it, and it does not require a ton of 4* recruits. Also, with a fluid transfer market, I think it is more possible than ever.
Think about it, GB did the exact same thing defensively. By year 3, we crushed ****braska and beat a way more talented Texas team. Even with the recruiting limitations, GB was able to win 4 of 5 B12 North. It only takes a few great recruits who can plug in your system, aka Jordan Dizon. It is a matter or patience and learning. My only wish is that the defense was not so young, across the board. In looking at this years defense, we have no players anywhere near the talent Evan Worthington or Drew Lewis. It will just take time.
This outlook on recruiting is why CU has had one winning season this decade.
