Who has produced a worse points earned per dollar spent, or new revenue per dollar spent? I'm open to arguments, but I have him so far in front he can't even see second place.
There's been worse ones in terms of intentions, look at Precourt. But in terms of competency - measured - who has had a worse ROI? Again, in a raw measured from rather than a "gee that guy sucked for x boneheaded move". I genuinely can't think of a single other person.
