Can you imagine the poor announcer on a 3vs3 all on the same field going head to head?
He'd be worn out by lunch the first day (What do you think Steve W?). I can more easily see 2 fields running simultaneously. This would be much easier to basically look at the progress of each field and highlight the more functional teams at work. I dunno, but yes this 3 team alliance needs to squeeze every drop out of their picks.
I hate to think of the dominator type strategy teams that your bound to wind up with that will want you out of the way. But I'm sure with a 3 team goal/game we're going to have to work together harder than ever. We need some good lessons in cooperative design.
Early on in FIRST I used to always think you needed to pick 1 thing and be the best at it. But last year changed that for me. And a 3 team mixed bag system would really require diversity. I'll put my Beatty hat on for a 3v3.
