Is it just me, or has KG become an arrogant SOB since he donned the shamrock? Sure, he’s a great talent. But what’s up with all the sneering and roaring? You’d have thought a three-year $60 million contract extension would keep someone from scowling so much. (Or maybe it’s the fact that the leprechauns can’t seem to win a playoff road game.) And as for that Gatorade commercial, you know, the one that’s run every other timeout — uncle! UNCLE! C’mon Kev, enough with the chest thumping. We know you got heart. But until you get a ring, lay off the histrionics.
