When I was young, I was an avid golfer. Not a good golfer, but an avid one. If I played 18 holes in the 90's, I felt pretty good. So... yeah... not good.
When I was about 17, I made a strange decision. I stopped playing 18, stopped going to the practice green, stopped playing with my driver at the driving range - stopped it all, but one thing. I went to the driving range every day and just played a 7-iron. Over and over and over. Don't know why I did that. But here's what happened: I continued to suck for several weeks. And then one day, BAM! Long, high, arching perfect 7-iron shots over and over. Every time. 175 yards, beautiful trajectory, backspin, the whole works. Every time. It happened over night. (And it bled over to my other irons, and I became a good golfer almost over night. But that's not the point.)
My point? It didn't really happen over night. What I witnessed was the completion of a long journey from 5 critical flaws in my swing, to 4 critical flaws in my swing, to 3 critical flaws, and so on. Until there were no such critical flaws. And then BAM!
You know what it looked like when I reduced my critical flaw count from 5 to 4? Nothing. I still sucked. Know what it looked like when i went from 4 to 3? Same thing: I sucked. It's only when I got to 0 critical flaws that the magic happened. That's what Nebraska is going through now. It's getting better, but it won't show up in wins and losses just quite yet.
There are a few other things that I could say that relate to exactly why the turnaround is taking longer than other turnarounds. If anyone is curious, I'm happy to share. But I'll leave it here for now.
