The Broncos secondary is one of the oldest in the league so bringing in Moore helps them add young talent. Moore is a true centerfielder with good ball skills. He has sideline to sideline speed with the abilty to close quickly. Moore is the best safety on the board and could have snuck into the 1st round.
Franklin will likely move into guard but I feel his upside is limited. He has potential but was incosistent and doesn't play as strong as he appears. It looks like John Fox is working hard to put his stamp on this team in order to establish a power running game.
