Locking up 20-year-old power forward Amir Johnson, hasn't been nearly as easy for the Pistons as re-signing Chauncey Billups.

Johnson was expected to join the summer league team in Las Vegas on Wednesday afternoon -- an indication a deal was imminent -- but he did not play.

The deal is still not done. The Pistons are believed to have offered a three-year deal worth as much as $10 million. It's possible that Bill Duffy, Johnson's agent, might have had interest from another team, maybe San Antonio. But the Pistons have made it clear they will match any offer.
