Fans don't get to pick the owner, but if we did, I am not really wanting the unicorn mentioned. That sounds like a recipe for a guy to come in and impatiently put together a 300 million payroll, have it not work out, and fire everyone and be left with a bunch of bad contracts and sell off a broken franchise that will take years to recover.

I'd much rather bring in a guy who'd spend up to the cap, and be willing to run over temporarily when it makes sense and can put together the personnel to build a team that is a perennial contender. That's the kind of owner that will build a fanbase and build a sustainable, successful franchise.
