Why does this blue-haired freak keep air-kicking the teams?! ACK!
Anyway, I was thinking about making a shepherd robot that would be fast and have wings that would deplot to kinda plow the balls to the human players, and push around goals and robots- what do you think? any major design flaws? (keep in mind it's just a cardboard practice robot, no need for details)

Sounds like a good plan to get some preseason work in prior to kickoff. You will already be a step ahead of some other teams.
In terms of drive train design, generally when you make something strong enough to push other robots around you will sacrifice speed. And vice versa. Might I suggest reading some of the white papers and threads about drive train design. This can help you begin to understand the differences between the different motors, advantages/disadvantages of different gear ratios, different wheel sizes, etc.
You don't have to get really fancy and do multiple speeds or anything like that. But it is good to know some of the fundamentals and learn from other peoples experiences before you start. Many times I have been on a team where we spent so much time getting a drive train to work that we had no time to make any subsystems so it is a good idea to spend some time before kickoff studying/experimenting with drive trains.
