I rarely watch a full game unless it's on a weekend when I am free. I usually have most of the midweek games on once my day is over and I have free time. Excluding the playoffs, I'd say I probably watch about 10 full games a year and some portion of 80 - 100 games otherwise. I almost never watch on delay. I'll just check in when it's live.
If I didn't have kids to put to bed or a slowing metabolism, I'd be watching a lot more Sox than I do now.
