Why would it be different than the coaches listed on their website?
Because they merged with another program.
That does not change the coaches for the teams. They may add a third 2021 team which most likely will be the HDD and that coach "probably" will stay with that team. Lavey was the A coach and Rao (former Riptide coach that stayed with his team) the B.
Are you with Legacy? Do you now this for a fact? If so, maybe 2021 is that simple, but not necessarily some other grades.
