Penn State and Wisconsin seem to be leading the way vs OSU B1G OOC home and homes...as they always have.
This is either

or you are full of ####.
Penn State hasn't played a good OOC team since 2011. You might have an argument for playing UCF in 2013 and 2014, but that was before all their recent hype. When PSU put them on their schedule, they had no idea they were getting a team a few years away from winning a national championship. At the scheduling time they were just a decent non-power 5 conference team, like playing a good MAC team.
It also wasn't a home and home series as one game was played in Happy Valley, but the other was played in Dublin, Ireland. Even if PSU had played at UCF, playing in Spectrum Stadium isn't known as being a tough environment for visiting teams anyways. In recent years, Pitt and Temple are the only home and home series with an OOC power 5 conference until you go back to their home and home with Alabama in 2010 and 2011 (which is awesome that they did that by the way). And in 2006 and 2007 they played home with Notre Dame (which again is awesome, and what an "elite program" should be scheduling). But it seems that since the Joe Pa era abruptly ended, they took an extended break from taking risks on their schedule. But that does seem to be changing in the future with Auburn, Virginia Tech and West Virginia scheduled for future home and home series.
Wisconsin should be commended for playing LSU in 2014, Alabama in 2015, and LSU again in 2016.
But none of those games were "home and home" games. Wisconsin did not have to go into Bryant-Denny Stadium, or into Tiger Stadium. Maybe BYU might be considered a decent OOC home and home series.. maybe. Oregon State and Arizona State were the only home and home series with an OOC power 5 conference I could find on their schedules in the past 15 years. They do have Notre Dame scheduled for 2020 and 2021, but again they avoid having to go into another schools stadium,
so even that's not a home and home series. Both games are scheduled for neutral sites. They are 6 years away from their first tough home and home series in decades when they have Alabama in 2024 and 2025, which I applaud them for scheduling, but seriously, if you want to be as good as your school acts like it is, then why take so long to do that?
Ohio State played home and home with: Oklahoma in 2016 and 2017; Virginia Tech in 2014 and 2015; California in 2012 and 2013; Miami, FL in 2010 and 2011; Southern Cal in 2008 and 2009; and Texas in 2005 and 2006. California wasn't great, but I would put it on par with playing BYU. And while VT didn't have great teams in 2014 and 2015, when that series was scheduled over 5 years prior, VT was consistently top 20 and sometime top 10 annually. So OSU was taking a risk scheduling a home and home series them, especially given Rivals.com has Lane Stadium as one of the toughest places for opponents to play. Oklahoma was ranked #14 and #4 when OSU played them. Miami was ranked #12. Southern Cal was ranked #1 and #3, and Texas was ranked #2 and #2 (and won the NC in one of those years). At the very least, OSU for years has almost always scheduled at least one home and home series with an OOC power 5 conference teams with strong histories of being ranked (California being the exception). 2019 is the first time since 2007 it hasn't happened. It begins again in 2020 with a home and home with Oregon, then Notre Dame (2022 and 2023), then Washington (2024 and 2025), then Texas (2025 and 2026). In 2025 they are playing both Washington and Texas. Some of them may not end up being ranked teams when OSU plays them, but Oregon, Notre Dame and Washington have all been in the College Football Playoff which is only five years old, and Texas was knocking on the door last year to get there. By 2025, I think they'll be even better.
I'm sure you can find schools that take even bigger OOC home and home series risks than OSU does. I'm not suggesting OSU sets the standard. But PSU and Wisconsin? Seriously?!?!?
So forgive me if I see your claim as being complete bunk.
