The Dallas Morning News (Eddie Sefko) reports: Fringe NBA players are on tour these days, making the rounds to see where they might have a shot at full-time employment next season. Most of the names are anonymous, but one that made a swing by American Airlines Center on Monday was of particular note: Pops Mensah-Bonsu… The Mavericks also brought in Richie Frahm, a respected shooter who has bounced around the league for several seasons and played 10 games for the Los Angeles Clippers last season.
