Even though it may be nice to have as many people as possible participate, you dont want the driver box overcrowded. Hugs and pats on the back can always be shared off the feild right after the match. That second coach is being eliminated because they are not really essential to the success of the team. Whoever said that their team switched off adults coaches every round so they all get a chance, there are about 8 rounds at a typically regional so everyone can still have a chance, and if you have more than 8 adults who are very active on your team, then the students are probably not getting to do very much. I don't mean to offend you, and maybe you do have a team where theres lots of adults and the students do just as much work, im just saying in most cases its not like that.
I think another reason that FIRST may have made this rule is that in the past there have been some overly aggressive and emotional coaches. I have observed this quite a bit on other teams. Theres definitly just as many good coaches out there, but say you are the poor driver who gets stuck with two self nominated negative coaches. One is easy to deal with, but two?
I know these arent very good points Im just trying to provide some insight on why FIRST might have done this.
Anyway for those adults who got the shaft this year, dont be too dissapointed, theres a lot of scouting to do and that is just as important, and doesnt someone need to schmooze with the other teams and advertise your robot? Teach the kids how to do it right.
