I think adding Mayo and West would be awesome and were not locked in long term to either players

The story Per ESPN

The Memphis Grizzlies are in advanced discussions with the Indiana Pacers on a sign-and-trade deal that would bring free agent Josh McRoberts to the Grizzlies and send guard O.J. Mayo to the Pacers, according to sources close to the process.

\Sources also told ESPN.com that the Pacers are making progress toward a two-year deal with free-agent forward David West in the $20 million range after West's sign-and-trade to the Boston Celtics got held up this week.

NBA.com reported Sunday that the Celtics-Hornets talks to send West to Boston via sign-and-trade are off. The Pacers, sources say, also have Carl Landry and Andrei Kirilenko alongside West at the top of their frontcourt wish list.

The Indianapolis Star reported earlier Sunday that the New York Knicks' pursuit of Jamal Crawford in a sign-and-trade deal with Atlanta and one more unspecified team was expected to put the Pacers back on the Mayo trail. Yahoo! Sports reported Saturday night that the Pacers had moved strongly into the bidding for West when the Hornets and Celtics could not immediately complete a sign-and-trade deal to land West with the Celtics.

The Mayo-McRoberts deal, if it goes through, is a re-run of the deal that the teams nearly pulled off at the trade deadline in February before a snafu in submitting the deal to the league office resulted in the trade collapsing. In that deal, Memphis was set to acquire McRoberts and a first-round pick for Mayo.
