Dorsey got fired. Daboll left for a HC job with the Giants in the offseason, although there was speculation he would have resigned and went elsewhere if he hadn't gotten it due to tension between him and McD.
Dorsey was just terrible in terms of his ability to call games and know how the flow of a game should go...it was just a mish mash of plays called whenever he wanted with no feel for when to call them or why or in what situations they would be most effective or how to set up the defense with playcall combinations and/or plays that looked the same that they showed them earlier in the game that are different, etc
Dorsey reminded me when I used to go out to clubs back in the day and you'd go to some clubs where the DJ knew how to get into a flow and maximize everything and take the crowd somewhere and then other clubs the DJ would just play whatever song in any order and completely wreck the flow of the night. Same songs, just no understanding of how to sequence them properly. That was Dorsey in NFL terms.
