NFL Week 4 betting preview: Which teams to play now, and lines like Cowboys-Patriots to watch for value later

I'm going to admit, this exercise hasn't gone great for me so far. My picks on Thursday have been hitting at a strong clip, but the early lines have not treated me so well, and I end up betting more money on a different aspect of some of the games I highlight on Monday by the time the weekend comes.

So I'm going to throttle down the amounts we are spending here early in the week. Sometimes less is more. A few of these spreads and totals have already shifted several points from Saturday based on game outcomes and injury situations.

Before you make any Week 4 picks, you'll want to see what NFL insider Jason La Canfora has to say. La Canfora has taken an early look at the games and found a number of best bets and lines to keep an eye on. One of the matchups he's monitoring? Patriots at Cowboys, which could be a big value opportunity if the numbers move the right way. You NEED to see his analysis before locking in any NFL picks of your own.
