The Broncos have signed 30-year old safety Renaldo Hill to a 4-year, $10 million dollar contract.  Hill played in all 16 games for the Dolphins last season and he made 77 tackles, defensed 4 passes and he had 3 interceptions.  Hill has now played in 110 games in his NFL career and he has made 474 tackles, defensed 55 passes, has 4.5 sacks and he has intercepted 15 passes (one of which he returned for a TD).  With the defense in shambles in Denver this was a good first signing to help them improve on that side of the football.
