I think one thing hasn't been highlighted enough, though it was touched on briefly, is the effect the scholarship limit will have on this. Yes, the P5's are going to steal the A10 stars after a year or more of experience. Since you are limited to 13 scholarships total, you have to forgo something to get that star. What is it that you give up, a possible star freshman. So those star freshmen will start out in lower places than they would have normally. Some P5 coaches have already said they aren't taking freshman anymore when they can get a known quantity from another school.
So, I think the overall impact will be that incoming freshman will (on average) start at a lower level school. The lower tier schools will get the benefit of having better freshman for a year or two before they move to a higher school. The higher level schools will get more well known quantities for fewer years but will forgo some star freshman. So, the lower level schools will become the minor leagues for the higher level schools.
