Under Armour CEO takes a swipe at Nike

• It's either sour grapes or a tip-off on a clever strategy as Under Armour (NYSE:UA) CEO Kevin Plank reacts to the loss of NBA star Kevin Durant to rival Nike (NYSE:NKE) in the gigantic $350M basketball shoe deal which was disclosed last weekend.
• Plank says he takes pleasure in seeing the Oregon sports juggernaut pony up an extra $150M to land Durant.
• The exec thinks a strategic opportunity will open up elsewhere in the sports world with Nike's war chest diminished a bit.
