Jose Calderon reportedly reaches 4-year deal with Dallas Mavericks

Detroit Pistons point guard Jose Calderon is close to a deal with the Dallas Mavericks, according to ESPN's Marc Stein.

Dallas had been one of the teams with cap room and in pursuit of Dwight Howard, but Howard informed the team they were out of the running on Friday. Dallas seems to have quickly moved on to its next target -- Calderon.

Stein reports that the deal is going to be for four years.

This would be a significant setback for the Pistons, who had made re-signing Calderon one of their offseason priorities. And even worse, because the Mavericks have so much free cap space they won't be motivated to work out a sign-and-trade deal for Calderon meaning Detroit will lose their incumbent starting point guard and have nothing to show for it.

Currently, the Pistons have only one true point guard on the roster -- Peyton Siva -- a rookie and late second-round pick.

Rodney Stuckey and Brandon Knight both have point guard experience but have not seen much success while in the role.

There are point guards Detroit will most likely turn their attention to on the free agent market including Jarrett Jack, Jeff Teague and Brandon Jennings.

UPDATE: Woj says it's a done deal and Vincent Goodwill has comment from Calderon's agent, Mark Bartlestein:
