The 1971 allegation, if one assumes it's true --- it's more than slightly disturbing.
I can easily ascribe motive to Paterno in 2001. Older guy, endebted to Sandusky a bit for helping his own career, scared of giving up coaching football because he knew the "next milestone in his life would be dying" (he was quoted on this all the time)
I can't ascribe motive as easily in 1971. What's motive then? Sandusky's just some late twenty-something, barely beyond being a kid. A 2-year assistant LB coach. Definitely not a vital cog in Penn State Football, Inc. as of yet. The 2nd Mile doesn't exist yet. Paterno has the prime of his coaching career ahead of him instead of behind him. The future is very bright for Joe.
So just throw Sandusky under the bus --- shoot, he deserves it anyway, he's assaulting young boys. Easy as 1-2-3, there's probably not even a short-term bump for Penn State football.
Of course, one does not have to ascribe motive. But usually there is a motive.
I don't know. It's kind of odd, right?
I can come up with 2 motives, but they're both honestly kind of crazy. (1) Sandusky, even in 1971, has something terrible that he can threaten Paterno with. (2) Someone else is threatening Paterno, telling him that nothing can be done regarding Sandusky.
