“It’s been a challenge because what the league has done over the last few years has been dramatic in terms of the style of play and the sophisticated offenses that you are seeing now,’’ Magic coach Frank Vogel said of his team’s struggles in trying to adapt to 3-point-heavy, “small-ball’’ lineups. “You see the offensive numbers just sky-rocketing league-wide. I don’t think anyone in the Eastern Conference has a defensive rating under 102 (points per 100 possessions). That just wasn’t that way a year or two years ago and it’s largely about the spread lineups that you are seeing. So it has been tough to play two bigs,’’ Vogel continued. “That’s why we went to putting (Biyombo) solely as the back-up center.’’
