I wouldn't fire anyone over this Martin/Incognito fiasco... but I want them all fired for "football" reasons. This team has been out-coached in the second half of every game; the only wins were due to the occasional big play on the field, and not anything that can be credited to the coaching staff. I can give Ireland a pass for missing on some draft picks, as that happens to everyone. But, Ross wanted to see major improvement this year, and Ireland basically wasted the entire draft. Sturgis is starting, but everyone else was injured, and/or a "project"; including the #3 pick in the draft. The o-line needed upgrading, but Ireland only brought in a few banged-up older Free Agents. Even though Miami led the league in giving up sacks, the coaching staff made no changes in personnel or schemes to try and fix the problem. In fact, nothing at all was done until after the meeting with Ross, when Ireland got McKinnie.
Oh, and the person who decided to make Martin the starting LT indirectly caused this whole mess. Martin was too weak to be starting; he's more of a project than a starter. If decent starting caliber linemen had been brought in, then Martin would not have been under intense pressure to perform immediately.
