My first thought: surprise.
Then I read all the comments, and I agree with those who say "low risk/potentially high reward." We all know he's a bit ... interesting ... at times
, but I also remember watching this guy and seeing him fly down the court and soar for alley-oops. Not a great rebounder, but we'll see. Good shot-blocker, great finisher, athletic. Why not give it a shot if he's virtually free?
And someone asked about "Shaqtin' a Fool" and said it sounds like Shaq trying to be punny but failing ... I agree. It's a play on "actin' a fool," but that wasn't readily apparent to me when I first heard about it. A bit of a stretch.
