I don't think everyone here is understanding the difference between a documentary and a TV Drama. The stereotypical movie or TV drama about sports involve the hero/heroine's underdog team beating out the "unfairly advantaged" team that has won the whatever level championship for the past whatever amount of years (the general exceptions are plots that follow some misunderstood hero/heroine trying to get onto the sports team, but this is about one of the rarest issues a student could have in FRC considering how desperate many teams are to get students
). I guess the producers decided that the easiest way to create the other team's "unfair advantage" (as well as using something that, like it or not, is a real controversy in FRC) was to use the Mentor built controversy. No matter how inaccurate it may be it is a easy way to imply the "unfair advantage" to the audience.
If it was a documentary on the other hand, such a portrayal would be unacceptable. While the movie or drama is just a source of entertainment the documentary's responsibility to portray truth shouldn't allow a serious portrayal of the controversy.
I do agree that it would be best if the episode does end up showing that the team's original understanding of the "mentor built" team ends up being inaccurate.
