Taylor is often conflicted with the advice he is given by local supporters of the team. After the team advances to the state tournament at the end of Season 1 under his leadership, Taylor leaves Dillon to accept a higher level job at a college, also in Texas, only to return to Dillon early in Season 2.

In the season finale Julie and Matt break up and go their separate ways. However, their paths cross once again in Season 5 when Julie goes to Chicago to see Matt after making some bad decisions. During her visit, they kiss and Matt gives Julie the belief that she should stop running from what she's done wrong. She again leaves and their relationship remains ambiguous.
