The price for Scola wasn't particularly high, from Indiana's perspective.
Pacers fans have grumbled constantly about the lack of productivity from Green, who still has two years and $7 million left on the free agent deal he signed last season, and Plumlee spent much of his rookie playing time with the Fort Wayne Mad Ants of the NBA D-League.
Bird believes that a better bench will help the Pacers continue to make deep runs in the playoffs, and possibly even get past two-time NBA champion Miami in the Eastern Conference. The Heat beat Indiana 4-2 in the second round of the 2012 playoffs and needed to win Game 7 to finally fend off Indiana in the Eastern Conference finals this year.
New Suns general manager Ryan McDonough called Plumlee "one of the best players" in this year's Summer League, where the big center averaged 10 points, 9.5 rebounds and three blocked shots. McDonough also said that Green will add athleticism and scoring ability to what is designed to be an up-tempo style under new Phoenix coach Jeff Hornacek.
Phoenix is undergoing a roster overhaul in what could be a lengthy rebuilding process.
"The trade is consistent with our stated plan to continue to acquire young assets," said Lon Babby, the Suns' president of basketball operations. "With this trade, we now have the potential of three first-round picks in the 2014 draft and five first-round picks in the next two drafts."
Plumlee gives the team a second young center. Phoenix used the fifth overall pick in this year's draft to select Maryland's Alex Len, a 7-foot Ukrainian who is recovering from right ankle surgery.
