It is very rare for the Denver Broncos to reunite with players, at least as far as my knowledge is concerned. But perhaps a player like Danny Trevathan could be an interesting fit for both parties involved.
But wait a minute, the Broncos already have two starting inside linebackers. That is true, but there is a chance that John Elway decides to part ways with Todd Davis without losing a lot of money. As it stands right now, Davis' contract has a potential out that the Broncos can exercise.
The Broncos have from now until March 18th to exercise the option of Todd Davis.
