The 49ers have signed 32-year old cornerback Dre’ Bly to a 1-year deal.  Bly played in all 16 games for the Broncos last season and he made 62 tackles, defensed 8 passes, forced 1 fumble and he intercepted 2 passes.  Bly has now played in 151 games in his NFL career and he has made 455 tackles, has defensed 136 passes, has 4 sacks, forced 18 fumbles and he has intercepted 40 passes (5 of which he returned for TDs).  This was a nice pickup for the 49ers as Bly can still play.
