I'll watch NFL this season...
...to track how my fantasy football team is going.
Beyond that, if it's not involving a former Purdue player, I usually don't care that much about the NFL. I consider myself today a half-hearted Saints fan, but that's just because of Brees. When he retires, I'll be officially without a team.
And no, I'm not going to root for the "Los Angeles" Chargers, even though they're local. I could have become a Chargers fan, but I HATE HATE HATE when teams sell out their market and move for more money. I kinda half-heartedly liked the San Diego Chargers, but I have no use for the LA Chargers.
