JJ wasn't fired by Jones.. they both agreed to part ways. JJ was tired of Jones meddling in football decisions, he wanted complete control much like Parcells did when he left the Pats. he got full control in Miami and built a championship caliber defense but he blew it when he traded down and got John Avery instead of staying put on landing Randy Moss. the way Moss played as a rookie he could of been unstoppable with Marino. the guy knew how to draft defense though. Zach Thomas in the 5th round, Jason Taylor in the 2nd round. Madison and Surtain in the 2nd round as well. Daryl Gardener.. he failed though at fixing the offense and the phins could never get far in the playoffs.
