It's sad, but also sounds like he was having major troubles before that. I believe report a good while ago suggested Thompson couldn't be left on his own, as he'd wander off.
Which didn't say it, but seemed to imply mentally he would get lost and not be able to find his way back.
He sounded like a great but maybe a bit boring human being.
And to try to set the record straight, he wasn't tight with money, he spent the money, it's just instead of over paying outsiders FAs, he'd over pay insider FAs. Which yes was boring, but he spent the money, and he even brought in Woodson, Pickett and others and sounded like he was #2 or #3 on a lot of deals. But he didn't sit on the money, he spent it and tried to win and put together some pretty good teams that had chances to win.
