If the coordinators are calling the plays, what exactly is the head coach doing during the games? I know he manages timeouts and decides when to challenge plays, but I'm curious as to how much he affects play-calling and what are his primary responsibilities during the game.
As a fan who only has one year of organized football in middle school, I don't have much in the way of personal experience to refer.
Note: This is not meant to downplay head coaching in any manner, nor comment on the work head coaches do during the week to come up with plans of attack with the coordinators and motivate his players to be ready for the matchups. This is also not in any fashion meant to be a comment on Coughlin (though using him as an example would be great since I hava better frame of reference with the Giants team than with other teams). It is just a general football analysis question.
Thanks in advance.
Discuss and assess with his coordinators and various coaches what is working and what isnt - and what is still planned. As the team shifts from offense to defense the coach will be analyzing what they are doing well and not doing well and make adjustments and advise the coordinators what to do - whether stick with the game plan, try this specific play, exploit this matchup, etc.. This includes input on the play calling.
Other items: who's injured or hobbling? who on the O line is getting their ass kicked and needs help? talk directly to players about specific plays and get feedback;
although coordinators call the plays coaches can be very involved in that process
Also make key decisions at specific points in the game
If D and O game plan is working... they may have little to no input... if game plan blow up... they may scramble to stay in the game
Or, is the head coach calling the the type of play, and the Coordinator chooses a play that fits the mold?
Examples
Offense (referencing the #1 option on the play):
"take a shot deep"
"medium-gain pass"
"Screen pass"
"play action"
"Shotgun formation"
"4 WR set"
"Running play"
Defense:
"play zone/man"
"blitz"
"rush 3"
And from these instructions, the coordinator then selects the play that will best suit the objective
