The Celtics  and Clippers were informed “days ago” that a deal involving Doc Rivers  and Kevin Garnett  going to Los Angeles is not permitted under league trade rules, even if the deals were separated into two different transactions, a league source told CBSSports.com on Thursday .
Speaking on ESPN Radio in New York, commissioner David Stern  said, “The teams are aware that the collective bargaining agreement doesn’t authorize trades involving coaches’ contracts.”
Stern added that there is no separating the two deals at this point because everyone is aware that the two deals would be part of the same negotiation.
“If you think those, at this point, having been all over the media for the last week, are separate transactions, I have a bridge that I would very much enjoy selling to you,” Stern said.
