WEEI had Wyc Grousbeck on the air and he dropped this bomb.
According to Celtics co-owner Wyc Grousbeck, they will have the financial flexibility to offer someone a full max contract next summer. Speaking with "Dale & Holley" Monday, Grousbeck did not give specifics, but he reiterated this fact by saying "there is a situation under which we could do that." Several high-profile players who would command a max contract are currently set to become free agents in 2010, including LeBron James, Dwayne Wade, Amare Stoudemire, Dirk Nowitzki, and Chris Bosh.
I'm not sure what he's talking about, since Roy Hobbes laid out very clearly the cap situation in his FAQ column. Perhaps he means convincing Paul Pierce to opt out of the final year of his contract.
Update: Here's a link with the exact quotes from the interview - for example:
Addressing recently swirling trade rumors: “What not many people realize is how many calls are made and received throughout the league. We had a starting five that went a record 27-2. We can also offer someone a full max contract to someone next summer.”
