Even after Matt Barnes(notes) announced himself as a Toronto Raptor on his Twitter account, the sign-and-trade deal that would’ve sent him to the team with a two-year, $9 million contract has fallen apart, a league source told Yahoo! Sports. "The sign-and-trade is dead," the source flatly said. Barnes could still agree to a new deal with the Raptors with the available money left in their midlevel exception, but there appear to be larger offers elsewhere for him. A source blamed the snag on a "miscalculation" in negotiations.
