Not unusual at all to not have announcements yet during the spring signing period. This goes for other schools, too.
Regarding the new president, somebody asked him at his hiring what his first 90 days would be like. He took a page from candidates like Wight and said his first 90 days would be spent listening and building relationships. Translation: don't expect major changes, if any, for several months or longer. That's a good thing, imo.
