One thing we know about Harris that is different than Snyder: he has other mechanisms for generating income other than the team and if he wanted to spend whatever dollar amount, he could do it.
What he's not going to do is spend recklessly.
Snyder wasn't cash poor or cash strapped, simply because of the revenue sharing nature of the NFL. But he also didn't have any other income streams to support the team if he wanted to front load spending. Harris does.
Harris also has a whole lot of other expenses because Snyder neglected the team for 30 years. So between buying the team, paying for a stadium, renovating a stadium which will be torn down, re-building Commanders Park (or whatever they are calling it), investing in other infrastructure, he's got a lot to be getting on with.
But between Harris and Mitch Rales, they have enough liquid cash to spend absolutely any amount of money they would want to. Remember, Rales is worth somewhere about 4.5 to 5 billion, in addition to Harris' estimated $12 billion. And Harris still has investments in private equity and other things which throw off cash.
For the HOG, it's entirely a decision on what they want to spend, because they have the cash or access to cash, to do whatever they want.
Snyder didn't have that. And, as we learned, he over-leveraged the team in order to do things like paint his air plane and support his lifestyle. Dumbass.
