I do agree that the ranking will drop as other schools fill their classes. That said, it will still likely be ISU's highest ranked class since the 70's. And, they have a good shot at getting a couple 4 star/high 3 star players like Kam White, Marquis Hayes, KJ Hamler, MJ Webb. The good thing is that they have most of the class full, so they can focus on some big fish and really focus in on need positions.
Campbell is definitely on the right track...just keep stacking good classes together and the wins will come.
They can also focus on '18/'19 etc..they already one '18 commit and have gotten some positive comments from a handful of others. People have mentioned how, at least on the surface, this staff seems to enjoy recruiting more than the last staff. That is huge because recruiting never stops, this staff seems tireless and that hard work is paying off. That energy and enthusiasm seems to be seeping into the fan base as well, I expect JTS to be as electric as its ever been when UNI comes to town.
