Joe opposed joining the Big Ten but was overruled.
Now THAT is completely false.
The champion (from the B1G side) for PSU's invite was then-Illinois President Stan Ikenberry. Paterno was actually at meetings in Ikenberry's house in 1989 where all of he, Bryce Jordan, and Steve Garban expressed PSU's interest in joining the conference.
Now --- Bo Schembechler. HE was against Penn State joining the B1G. Schembechler was rather loud about this opinion.
But then-Michigan President James Duderstadt rather famously never consulted Schembechler as to his opinion, nor even told him that a vote was taking place.
