Yes, it's a complete stretch that OSU & UM had a hand in the 1969 revolt....
I have talked about this at length with two long-time friends of mine who were on the 1969 team. Both of them told me that Pont wasn't so much the problem, but instead, a couple of his assistants. According to my friends, many of the players on the team thought it was very clear that two Pont assistants were not going to give some of the black players much playing time... even though it was obvious that they were better than the... white, guys... playing ahead of them... The way I understood it was that Pont turned his head and let his assistants do what they wanted. Even though Pont tried to get them back, it back-fired and the boycott came about.
It appears Pont wasn't the real culprit.... Thinking about it now, I get the feeling Pont pulled a Paterno, kinda, and thought it would all go away... I might be wrong about that but I trust my friends knew what happened since they were on the team at the time.
