I don't know where you are seeing "no P4 offers" at. When I look up the bios, I see Arizona, Arizona State, Northwestern, Minnesota, Cal, Colorado, etc in their offers. And the lack of offers some of these guys are getting are due to regions and most bigger schools mostly being west of the Rocky Mountains and not sending scouts to those areas. A USC is getting 4 and 5 star guys so yes, they are going to look past them and expect them to walk on. But these guys are on the same caliber of pretty much any Big 12 or ACC schools recruits outside of Miami or Clemson.
