I've always been hyper-critical of those who watch games nine hours a day, simply wondering, "Who the heck has the time?" Given the dozens of other things you should be doing: 1. Tracking your exposure on games.
2. Betting select games in live wagering.
3. Betting second halves.
4. Shopping for Lines on games coming up later in the day (and occasionally racing to a book at top legal speed to get bets in!).
5. Prepping/updating power ratings on Sunday for opening lines that go up that afternoon.
6. Maybe having time to use the bathroom … or eat. Maybe.
