There is a difference between academically weak and lazy students. Based on what little I know about Fab, I'm not sure that he doesn't fall into the latter category as opposed to the former.
With respect to the NCAA clearinghouse; it's not like you're talking about the NCAA holding up the kids that present as "standard" cases. It is typically the kids that present extremely difficult / unique circumstances. They've been to multiple high/prep/charter schools. Some are coming from foreign countries. Just because a kid went to a school doesn't mean that that school was legitimate or had any type of certification of its programs. This is an area that I don't feel like I really know enough information about to say that the NCAA should act more quickly.
Did the kids and schools deliver the materials required by the NCAA to complete their evaluations in a timely fashion? Were the materials that were delivered truly what was required? Was it all tied up in a neat bow or was it a mess, did the material provided raise questions that required further investigation.
Clearly the athletes and coaches recruiting those athletes are going to scream foul...but are people who truly understand the situations (ie. information requested, information provided, standard that must be met) crying foul? I'm not so sure that they are.
