Jessalyn Gilsig | Shelley Hayes
Not much is known about Tami Taylor’s origin story. Nothing is revealed about her past, her education, or her family. However, that came to an end in the second season when Shelley Hayes, portrayed by Jessalyn Gilsig, showed up from seemingly out of nowhere.
Shelly was Tami’s younger sister. She showed up to help Tami take care of her newborn daughter, Gracie, for six back-to-back episodes before departing from the show for good. One day, we thought she would become an important member of the Friday Night Lights cast. The next, she was out of our lives. It was pretty strange, to say the least.
