Pacers president Larry Bird gave first-year coach Nate McMillan something Indiana was missing. In Bird's opinion, point guard Jeff Teague was an essential addition in the offseason overhaul that included firing coach Frank Vogel.The Pacers acquired Teague from the Atlanta Hawks in a three-team trade that sent the draft rights to first-round pick Taurean Prince to the Hawks. As part of the deal, Pacers point guard George Hill went to Utah. Indiana also acquired forward Thaddeus Young and signed unrestricted free agent Al Jefferson to a three-year, $30.5 million contract. All three players officially joined the Pacers on Thursday, as the NBA moratorium on acquisitions was lifted."With Jeff, we think he brings something we haven't had in a true point guard," Bird said of the Indianapolis native. "We think he fits in with what we're trying to do. He has speed, the ability to create for others and he can score."Last season, Teague averaged 15.7 points and 5.9 assists per game. In 2015, he was named to the NBA All-Star team.Young was a first-round pick of the Philadelphia 76ers in 2007. Like Teague, Young is 28 and has career averages of 13.8 points and 5.5 rebounds per game.Jefferson has never spent more than three seasons with a team. A below-the-rim post player, his signing seems to signal McMillan will play some slower-pace, half-court sets while primarily preferring an up-tempo offense. Jefferson, 31, was drafted by the Celtics but traded to the Minnesota Timberwolves, where he worked under former Bird teammate Kevin McHale. Last season he was limited by a knee injury and served a five-game suspension for violating the substance-abuse policy and averaged 12 points and 6.4 rebounds per game. He also has a history of chronic foot problems.
