This is true. Cooper was going to go to Ole Miss like his dad. Rumor was Cooper was better than either of them. And Peyton himself said that if Cooper hadn't of gotten hurt, he likely would have gone to Ole Miss as well. And of course, Eli ended up there.
The narrative that they all did their own thing is true, but it wasn't going to be that way. Cooper getting hurt was the turning point. Arch doesn't have the same kind of pressure as Eli or Peyton because while his dad is a Manning, he doesn't have the level of fame or commitment that Peyton or Eli's kids will have since their dad's did play at a school. JMO.
I'm certain that Marshall will go to the place that is truly best for him. And that's what we should all want.
We just also want Tennessee to be that place. Hopefully, by the time Manning gets here, Milton/Hooker/Aguilar/Merkingler/GMac/Brandon will all be in the league and doing well, and UT will be a championship winner/powerhouse
