I would be interested in hearing the opinion of the SciOly community pertaining to the planning and execution of the 2017 national award ceremony. I found it somewhat degrading in how they only permitted a coach and a captain to come on stage when they recognized the 7th-10th place teams. All in all it felt rather rushed and didn't seem to provide the degree of recognition deserved by the hardworking individuals who placed (in an event or within a team) at nationals.
First, I would remark that this is consistent with past years. They did not shortchange teams this year after recognizing teams in the past.
To actually address your question, I think their goal was to strike a balance between moving quickly through the 20 team awards they had to announce and recognizing each team appropriately. If I remember correctly, the ceremony had already been going on for two and a half hours. Personally, I think they struck the right balance.
