Hell, even the two sports owners most notorious for being cheap have their teams currently in line for at least a shot at a championship right now (Mike Brown and Donald Sterling). Just because we have to deal with a cheap owner who cares more about profit than winning doesn't mean we have to throw our hands up assuming it'll never happen, nor does it mean we have to assume that (even if not top priority) that they don't want their team to win at all.
Really it was that James Harrison 99yd return on that terrible too cute Norvish gimic play before halftime that cost them a Super Bowl.
