For as long as I can remember, I've been hearing the same Dvar Torah on Parshat Noach. Everyone always talks about Rashi's comments on נחַ אִישׁ צַדִּיק תָּמִים הָיָה בְּדֹרֹתָיו״", "Noach was a perfect and righteous man in his generation." Rashi gives two possible interpretations of this quote. The first is a "favorable" interpretation, proclaiming that if Noach could be righteous in such an awful generation, how much more righteous would he be in a great generation? The other side is a more negative interpretation, stating that while Noach was great in his generation, he would be nothing but average in a generation like Avraham's.
