The Dolphins requested permission to speak with Saints defensive coordinator Dennis Allen, according to Ian Rapoport of NFL.com (on Twitter). This marks Allen’s first known interview for a head coaching job in this cycle. 
Allen replaced Rob Ryan during the 2015 season as the interim defensive coordinator in New Orleans and was retained the following offseason. The Saints’ D has made big strides since then, so it’s no surprise that Allen is in the mix for a move back up the ladder.
In 2018, the Saints’ defense ranked second in the league against the run and tied for fifth in the NFL in sacks. Allen may have to explain what went wrong in Oakland – he went 8-26 in two-plus years – but his recent results are impressive and could vault him into the top job in Miami.
