As for how much financial stability Blitzer would bring to this franchise...
He's been with Blackstone, a very successfull and cutthroat organization for thirty years, and is head of its tactical acquisition depth. Hes been good enough to amass about $1.6 billion for himself, but thats not the big number. Because of his successful connections in international business, he has a Rolodex with enough names to buy all of MLB...lol.
He should have little problem with putting together a very well heeled group of partners, should he become majority owner. Within the sports world, he has been the second man in almost all the acquisitions he has been involved in. It isn't clear whether he is moving to the forefront here, or in the end will still be riding shotgun. In either case, his personal wealth is secondary to the amount of other peoples money he can control.
For the financial historians, this is how the House of Morgan (J P Morgan) operated. Use other peoples money to eventually make your own.
This news is 90% very good, and 10% very bad. The good is that ventures these kind of people take over usually in the end make a lot of money, although there is sometimes a lot of pain involved. The bad is that there are times when an acquisition is stripped of all its value and destroyed.
The biggest question will be whether Blitzer wants this franchise to win on the field or merely serve as a guaranteed profit maker on the back end...because, win or lose, no franchise loses value over the years.
