I don't doubt that. I think the story that came out yesterday underlines how resistant he was to selling though - and there's never been any real info showing the league 'forced' him out (short of major crimes, I'm not sure they could have). There was some noise from a couple other owners about the possibility, but owners voting other owners out is not very likely because of the precedent it would set.
Snyder's wife and kids were the driving factor in him finally letting it happen. I would bet my life on it. They are the only thing he puts before his own petty, selfish interests.
