The Pacers offered a five-year, $44 million contract to Stephenson, but sources said the versatile shooting guard believes he's worth much more.
Stephenson averaged 13.8 points, 7.2 rebounds and 4.6 assists last season -- all career highs for the four-year player.
"Lance and his representatives aren't sure they're going to be able to reach an agreement with the Pacers," a source said. "It's clear they want him back and he wanted to go back, but they may not be able to come to terms."
While money is a factor, Stephenson will not simply go to the highest bidder, sources said. He wants to go to a team that is either a contender or a competitive up-and-coming club.
The Pacers pulled out all the stops Tuesday by hosting Stephenson and his family at a local theater and surprising him with a movie about his life.
With lucrative contracts already committed to Paul George ($15.8 million), Roy Hibbert ($14.9 million) and David West ($12 million), the Pacers feel they are offering Stephenson as much as they can while remaining financially prudent.
