To be clear it is not Nebraska's fault that the kid didn't qualify - it is Nebraska's fault that they decided to take a commitment at a position of need in a small class from a kid who was never going to qualify
Except how do we know he was "never going to qualify"? He was obviously at risk, but I highly doubt the coaches would have pursued it if they thought there was no chance of him qualifying.
This is reading between the lines a little, obviously, since I have no inside info on what the exact situation was; but based on his comment about how he could have been a partial qualifier and he decided against it. Regardless of whether or not that is true, or him just talking it up, the fact that he would even say he decided against it, makes me think that he simply didn't want to put in the work required to become a full qualifier and be able to play. It makes me think the coaches looked at his ability, and his qualifying situation, and thought if he put in to some work in the classroom, he would be able to qualify, so they decided it was worth the risk. If they are guilty of something, maybe it's overestimating his desire to put in the extra work required for qualifying.
The fact that in that little article he shared, he essentially tries to place all the blame for his situation on everyone else, and takes none on himself for not making the qualifying grade, makes me think he thought he was going to be able to coast and not do any extra work, and was upset when that didn't happen. Him being upset because he was mislead and thinking he could have qualified elsewhere, when this an NCAA thing and not a Nebraska thing, is just the icing on the cake for me. That's proof to me he didn't want to do the work and decided he would blame everyone else for his problems.
Clearly, in hindsight, the coaches should have passed on him, but again, I highly doubt they would have pursued it if they thought there was no chance of him qualifying, just to be able to get a highly ranked player in the class. By the same token, however, if the coaches had decided to pass on him, and he committed elsewhere, and did do the work and make the grade and get on campus; I have a feeling a lot of the same people being critical of the coaches for ever taking him, would turn around and have been critical of them for not taking him. I'm sure we would have heard stuff like "Even if he is a risk to qualify, if you think there is a small chance he would, you have to take someone that talented".
