I have a long-running theory that Donovan's elaborate and varied choice of shoes throughout the season has negatively effected his play at times.
He seems to lose shoes on the court more often than any other player. He often has to stop to re-tie them, to adjust them, or to chase them down when they fling off his foot. I've also seen him change shoes mid-game after having mobility issues.
I have to wonder if unfamiliar and untested footwear has contributed to his current foot problem. I wish he'd just pick one reliable pair of shoes and stick with them.
