I think it's an uphill battle. Giffey seems like he has been coached his whole life to be solid above all else - he takes very few risks. He'll shoot his shots when he's open, but he won't try to create his own or shoot when he's not in his comfort level. He gives you neither assists nor turnovers, because he makes the conservative pass. He plays good position defense, but doesn't gamble much on blocks or steals.
I kind of think that all through his career, through German youth teams, international competition and his early years at UConn, he was always the fourth or even the fifth option on the floor, so he's been coached accordingly. His key to staying on the floor with German national teams, and with us too, was to take good shots, not make mistakes, and stay within himself. Most of our other players have been the man on their HS or AAU teams (or both) and probably have to be reined in a bit. Giffey's the opposite - when he tries to force things, he looks less comfortable. If he had this type of season as a sophomore or junior, there would be more time to coach him out of his shell, so to speak and get him more comfortable taking some risks.
