The rumor in one Western Conference front office Monday afternoon had it thatÂ Jannero PargoÂ was about to agree to — or perhaps already had agreed to — a deal that would have brought the backup point guard to San Antonio. Ah, but not so fast. Pargo’s agent, Mark Bartelstein, acknowledged ongoing talks with theÂ Spurs, but said his client has yet to agree to a deal with anyone. TheÂ SpursÂ spent the lion’s share of their mid-level exception to sign former Washington guard Roger Mason Jr. — another Bartelstein client — earlier this summer. The team still has a $2.9 million biannual exception at its disposal, more than double the $1.08 million Pargo would have earned next season in New Orleans had he not opted out of his contract.
