If you're a full season behind, and you want to maintain the tradition/ practice of naming all-area teams, I'd run a photo of the POY and then run the selections in an agate package.
Don't call attention to the disorganization of the previous staff by running a big package on all-area teams several months out of date.
Call the area ADs and explain to them, "the whole process was already months behind schedule when I came in, we do intend to continue to run them in the future, so we decided to run them in a very limited format."
After that, dust your hands off and resolve that all-area teams in each season absolutely must run no later than the beginning of competition for the next sport season.
That's a drop-dead deadline. Theoretically ideal deadlines may be very different.
I'd generally aim to pick your honor teams within a week or two of district tourney play in each sport and aim to run them within a few days of the elimination of your last team: this allows you to make adjustments to the teams based on performances in the state semis or finals.
Some people are adamant that state tourney performance should not be taken into account when picking A-A teams, but to me that's nuts; state tourney performance is pretty arguably the most important thing to base player assessments upon. So there's a decent argument to hold off running your teams until your last team is finished in tourney play.
Although it's probably very rare that any player who delivers a real difference-making performance in a state final wasn't going to be somewhere on your honor teams anyway.
To get all-area teams selected, written, and shot (photographically) on schedule, the SE has to really crack the whip to get those things out and not short shift daily coverage and previews for the next season (if you do them).
Whether the stories are assigned to be written individually or as a group effort, preliminary work ought to begin no later than midseason.
One result of the dramatic drop in news hole has been a major cutback of the over the top graphic packages and run-on-forever selection stories.
In the olden days for instance, in basketball you might pick a dream team, all-area teams in 4 classes, and then second teams, HM, etc etc; you might be organizing head shots and group art for 60 players, then writing features on the Dream Teamers, POY, COY, and capsules for second teamers, agate lists for HM.
That crap's out the window now. Most papers I've seen the past few years run a picture of the POY and that's it. A select few still do a group pic of the Dream Teamers, but not too many. Stories have been cut way way down too; now you have a feature on your POY and agate lists for everybody else.
