How about:
-an good, inexpensive but hard-to-find wine (you're from CA, so there might be lots of stuff you can get ahold of -- and if BIL is from out of CA, that they might not be able to find in their area)
- a gift card to a place that sells CDs/online music (itunes, borders, etc.)
- a wine stopper (a lot of people don't have one of these -- for keeping half-used bottles of wine fresh)
-and uh ... football ... yeah, someone else better advise on this one.
