There has been some very cursory contact between the Saints and representatives for wide receiver Devery Henderson who played his first nine years in New Orleans before signing with Washington this spring as a free agent and who was released last week. But it’s not a given yet that Henderson 31 will rejoin the club with which he entered the NFL and which perhaps could use a deep threat because of the recent knee injury to Joseph Morgan. A Saints official said the club is “checking out some things” on Henderson but the interest isn’t huge yet. A former second-rounder Henderson started just nine games and had only 22 receptions in 2012. Both were his lowest totals since 2007. The New Orleans coaches might still want to get more of a handle on young wide receivers such as Kenny Stills Nick Toon and Hakim Saalim before reaching for a veteran.
