It is already hard to get hard to get "those type of teams" on your schedule. I have my doubts that it will be hard to get North Carolina State and Minnesota and Vandy and Iowa State and Mississippi State on the schedule. And a few Pac teams seem to like to come east from time to time, so we need to be on top of those opportunities, but I also don't buy that P5s will only schedule others because among other things Michigan and Alabama have gotten used to having 7 or 8 home games each year, and that isn't happening if they schedule each other. What we are really talking about here is about a dozen schools, maybe 18 who move the needle. Then there is a 2nd tier that are good gets but not on the same level as the top ones. But they are already difficult to schedule. If you go through the P5:
ACC: Florida State, Notre Dame
2nd level: Miami, Clemson
B10: Michigan Ohio State Penn State
2nd level Michigan State, Nebraska, Iowa
B-12: Texas, Oklahoma
2nd Level: none
SEC: Alabama, LSU, Auburn, Florida
2nd Level: Texas A&M, Georgia, Tennessee
PAC 12: Southern California, Oregon
2nd level: UCLA, Stanford
there is probably a 3rd tier which would include schools like Wisconsin, VaTech, Missouri, south Carolina maybe K-State sneaks onto level 3, as would non-P5 BYU. The way I look at it, you'd be happy to play these teams and it will be a big time atmosphere but it won't be Michigan. And under no circumstances would you even think about doing a road game without a return.
If you went through each league you could probably add another couple of teams that are relevant now, but don't have the long term cache of a Southern Cal or a Texas. I'd actually put Oregon into that category. Give them the Paul Pasqualoni as coach and they will very quickly become just another team with funny uniforms. Whereas the A-list will still be the A-list even with Pasqualoni running the show. In fact Miami is fast reaching the point where it is just another ACC team and might be more a 3rd tier "name" now. Oddly Clemson is probably more high profile than VaTech which is a better program over the past 15 years, too.
