The Denver Broncos have captured the attention of the sports world, but their lead assistant coaches have captured the attention of the rest of the NFL. Both of the Broncos coordinators have been targeted as candidates for head coaching vacancies League sources have confirmed that the St. Louis Rams, who fired Steve Spagnuolo a day after the regular season ended, have contacted the Broncos for permission to speak with defensive coordinator Dennis Allen about their vacancy. Allen has been an NFL assistant for 10 years. This is his first year in Denver. Earlier, the Jacksonville Jaguars, who fired Jack Del Rio during the season, had been connected to Broncos offensive coordinator Mike McCoy. The Broncos have said that Allen and McCoy will be allowed to interview with teams, but not until Thursday afternoon.
