Serious question:
Why, do you think, OSU and Michigan have no trouble setting up h-h with Oklahoma, Texas, Alabama (among others)?
And USC with Ole Miss, ND, and LSU
UCLA with Georgia and LSU
UW with Tennessee - and Oregon with Oklahoma State and Baylor (even though both of those schools are also maintaining "rivalry" games w Oregon State and Washington State)
MSU with ND - Maryland with VaTech and UVA - Nebraska with Colorado, Tennessee, and Oklahoma - Wisconsin with Alabama, ND, Pitt, and Utah - Purdue with ND and UNC?
Probably a rhetorical question, as everyone knows why. It is a deliberate decision to maximize opportunities for "W"s. Penn State is not, certainly, the only program that chooses that option.
Personally, it is of little to no concern for me (so long as folks are willing to continue to write out checks and fill the stadium) - and some folks may love it, others hate it. But it is what it is.
