Why not pickup one of these guys?

Jeff Adrien, Dwayne Jones, or Earl Barron. I don't know get the point of having Marks. All of these guys might actually be able to log a lot of minutes. Adrien is undersized but produces pretty well, in the mold of Paul Millsap. Barron got some good run with New York last year and actually was a starter for the Suns for awhile this season. Jones owned on the boards in the D-League and seems like a good defensive player as well. Marks is decent at mid-range shots and keeping the bench warm but not much else, and has exactly zero potential.
