Dude, wake up. Its the Yacht.
Kidding, it makes perfect sense like you say. Jerry would have the perfect transition with his son as his proxy, McClay and Garrett as the smart guys in VP roles and then Richard stepping in as Head Coach with some of the best personal leadership qualities in the NFL.
That is a lot of sharp people in place to run things.
Another thing I can't help to think about. I've always felt this way about work-life balance. No matter how rich you may be, you can't buy time. We have only so much of it to enjoy on this world, rich or poor. If I had Jerry's money, I'd have retired a long, long time ago. He has only so much time left, does he want to soend it working until he drops? Or does he want go maybe step back and smell the roses? Seeing him purchase that hadn't gives me a smell the roses, enjoy the fruits of your labors vibe.
Otherwise, it's incredibly dumb to spend so much money on something you'll use so little.
