If the goal is to familiarize your team members with the history of FRC robot design get the kids to do the research! Using blue alliance, chief delphi maybe even youtube the students would get more out of actually doing the research than being told what is good.
I conducted a similar activity recently with our strategy pre-season sub-team where we looked more at performance than at design. However this gave the new students an opportunity to get familiar with certain teams and this process could easily be adapted to fit your design idea. Pick a topic and ask each team to research and present on it, this could be done in an hour or so or more time depending on how in depth you want the information to be.
I hope this helps, if not sorry for not answering your question
