Agents for holdout wide receiver Vincent Jackson say the Chargers blocked a recent trade attempt. "The reason the deal didn't happen was because the Chargers were asking for too much," Jackson's agent, Jonathan Feinsod, told the San Diego Union-Tribune. The Chargers, who control Jackson's rights, have final approval on any trade involving the player. "We have no idea what the Chargers were asking for in return," Feinsod's partner, Neil Schwartz, said. "From what they told us, they and the Chargers could not work out the trade."
