The Miami Dolphins have fired offensive coordinator Bill Lazor, per NFL Network’s Ian Rapoport. The Dolphins were expected to contend in the AFC East in 2015, due to some big-name acquisitions on defense and the expected development of quarterback Ryan Tannehill on offense. Instead, Miami are currently bottom of their division with a 4-7 record, which has prompted the team to already fire head coach Joe Philbin and defensive co-ordinator Kevin Coyle. Now OC Bill Lazor joins them on unemployment line, the last holdover of the coaching braintrust that started the season leading the team. Under Lazor this season, the Dolphins’ offense was 25th in yardage and 27th in points, while Tannehill has regressed in completion percentage, interception-per-pass ratio and in passer rating. The Miami offense initially looked to have something of a turnaround after Philbin was replaced by interim HC Dan Campbell, with huge one-sided victories against the Titans and the Texans. This proved to be unsustainable in the end, with Miami going on to lose four of their next five games. Lazor’s role will be filled by current QB coach Zac Taylor until the end of the season; this will be Taylor’s first time in his coaching career at any level to hold the offensive coordinator role.
