What reason would there be to wait until after signing day except to secure a recruit that would otherwise decommit?
possibly he needs a bit of time to step back from the situation and evaluate things.
talk to people he trusts and values their opinions and come to a decision of what needs to be done and how is that to be accomplished.
as flyfishing frog pointed out the simplest side of that equation is to fire someone except for two things.
first, you leave yourself with a reduced staff going into the stretch run before the first signing date and susceptible to other programs cherry picking your commits.
i have been a part of a sales staff that knew by the start of the new year we would all be gone, but you still have to keep doing your job. not easy and there were some calls from people after the purge, but none of those who called followed me elsewhere and a large part is they choice the company and not me and the company continued after we were gone.
second, it is very possible some of the staff gary would like to bring in to talk with an gauge their interest are still coaching and are out on the road recruiting.
gary from the outside appears to be a few things, but i think gary seems to value the code of values i hear the older coaching friends i have talk about in that there is a right and wrong time to contact people about staff openings.
i could be all wrong on all this, but i do suspect this situation is much akin to the old saying about a duck swimming on a pond
