The Dolphins have reached an agreement with defensive coordinator Dom Capers on a deal that will make him the highest-paid assistant coach in the NFL. Capers' new deal is for three years and an estimated $8.1 million, team sources confirmed. His salary in 2007 will be $2.6 million, equal to that of Redskins assistant head coach/defense Gregg Williams, but Capers will get raises of at least $100,000 per year in 2008 and 2009. Capers' current deal was set to expire on Sunday; he would have been able to talk with other teams, but he would not have been able to sign with another team until Feb. 1. Also, Jets offensive coordinator Brian Schottenheimer has emerged as a finalist in the Dolphins' search for a head coach, sources confirmed.
