Sure, especially with FSG pursuing and acquiring other businesses and growing their properties well beyond just Red Sox/Fenway - they operate from the business side first.
As opposed to Cohen, who is just a crazed fan with ultra deep pockets.
But when you operate from a business perspective first, that doesnt mean that you never spend/take-risks. It just means its more strategic / calculated.
Of course, they will open the vault again. There are times to invest in your business and times to draw from it. Good business is not "always be cheap, never spend money: but its also not "spend , spend , spend, wins first, fans first"
