I like this idea too. Maybe I want to go on vacation and I won't have any computer access for a week or two. I can set up my game strategies ahead of time, it would be useful to do the same for scrimmages. Personally, I'm not a flag chaser, but it would help if I could automatically accept a scrimmage and be able to set up a lineup.
I saw some of the comments about being active, but for someone like me who can have 2-3 14 hour work days in a row, sometimes I don't want to get onto buzzerbeater and just want to go to bed. I already get penalized for having a life and responsibilities in terms of not being able to upgrade my team as well since I don't always have the time to go through the transfer list.
Interesting side note, buzzerbeater isn't recognized in the forum spell check. Just thought that it would have been common enough to be added to the forum's dictionary.
