I'm the opposite. My sports calendar is always full, as I'm a complete junkie:
Jan - NFL, College B-ball
Feb - College B-ball
Mar - College B-ball, but starting to think about MLB
Apr thru June - MLB, with some NBA and NHL thrown in
July and Aug - Nothing but MLB
Sept and Oct - MLB and NFL
Nov and Dec - NFL
I love that there's always something going on I'm interested in. My wife hates it.
