I wonder if Reggie McKenzie gave a bunch of free agents a take it or leave it date, as the Raiders general manager just signed his fourth player on Tuesday. After signing free agent cornerback Mike Jenkins and re-signing defensive end Andre Carter to one-year contracts earlier in the day, Oakland inked free agent safety Usama Young and re-signed slot cornerback Joselio Hanson to deals. Young, 28 next month, played the last two seasons with the Cleveland Browns, posting career bests of three interceptions and 1 1/2 sacks in 13 games in 2012. Pencil him in at starting free safety. He spent his first four years in the NFL as a reserve for the Saints, where he played under Raiders coach Dennis Allen (then a secondary coach.) Hanson, 31, joined the Raiders after being one of the final cuts by the Eagles before the start of the 2012 season and spent most of the year playing out of the slot. Adam Caplan of TheSidelineView.com was the first to report Hanson’s signing.
