NFL Week 4 Best Bets to Consider
Now that you have claimed your betting bonuses, it’s time to use them on some NFL betting odds.
Justin Jefferson Special at ESPN BET
I’m not a huge fan of pre-made parlays or specials, but this Justin Jefferson special at ESPN BET feels like a fair deal with a good shot at cashing.
Jefferson to record over 69.5 receiving yards and score a receiving touchdown at +190 is the bet. Jefferson is still one of the best in the league, and he’s publicly beefing with Packers’ CB Jaire Alexander. I like that.

Bills Moneyline vs. Ravens: +115 at Fanatics Sportsbook
This feels like a WTF situation: Wrong Team Favored. The Bills have started the season off incredibly strong, with a pair of blowouts and a win against an Arizona team that’s probably better than we initially thought.
Baltimore, meanwhile, has struggled late in games. While I can forgive the loss to the Chiefs in Week 1, I can’t forgive that Raiders loss. The Ravens one win against the Cowboys also doesn’t really impress me.
It’s a week-to-week league, sure, but the Bills are clearly the better team right now.
