To figure out what they were going to say and do, and relay it to everyone involved. They did the little "program" of sorts with the HOF'ers coming onto the field, etc. They had to get everyone where they wanted them. I doubt their concern was concession income, but it probably did involve trying to do something to appease at least parts of the crowd a little. Coming out and saying; "The game is cancelled. Bye." could have turned the crowd into an angry mob.
