If an owner isn't willing to spend whatever it takes, including paying the tax, they shouldn't be an owner.
Dan Gilbert, for as little as he knows about basketball, is the model owner in my opinion.
In the past, Wyc was willing to pay the tax, but that was under a different tax structure. Hopefully he is willing to put his money into the product, since you know, he's currently raking in money hand over fist, in addition to the exponential growth in franchise value he has seen during his tenure.
