 What is up everybody, welcome to week 18 of the NFL season and the fan duel hurry up. I am Brandon Gadulla, I'm the managing editor at Numberfire.com and I'll be breaking down my three favorite stacks for the week 18 main slate. Stack number one is Matthew Stafford and Cooper Cup. This week we can focus on teams with motivation to play starters. That leads to big upside historically from stud players as past optimal lineups in week 17s have shown. That makes me want to allocate Salary for Cup who has 12 catches and 136 yards away from setting single season NFL records. I know he's kind of said he feels weird about breaking them because of the extra game, but I think he's still going to want those if he can get there. Cup has double digit targets in all but two games this year with at least 95 yards in all but one game. Stafford has been struggling a bit which I get the hesitance maybe to want to play him, but again this game has relevance for the Rams who are playing for seeding and even against top 12 past events Stafford has averaged 278 yards and 2.1 touchdowns. My second stack for week 18 is Tom Brady and Rob Gronkowski. Brady and the Buccaneers are losing some pass catchers who are key for this team but that hasn't really led to a significant slowdown just yet. Brady is an outside shot but is 488 yards from setting the single season passing record so we kind of have that angle but even without that there's plenty to like against this Panthers defense that's just a round league average. Brady even against top half past the offenses has averaged 334 yards and 2.1 touchdowns. Again there's an outside chance of the record but this game matters to the Bucs and head coach Bruce Arians has said that they're playing to win. As for Gronkowski, bounced back in a big way with his usage in week 17 with 11 targets giving him double digit looks in two of his past three games. His target per route rate of around 24% suggests a high ceiling of targets again as his roll continues to expand and stay strong while the team is without Chris Godwin and Antonio Brown. My third stack for week 18 is Kyler Murray and Christian Kirk. Across 10,000 slate simulations this stack emerged as the second best value stack in my model. The only one to beat it in terms of value was Kyler Murray plus Titan Zachard. So it's kind of a two for one in a way but I don't want to overlook Christian Kirk this week just because he hasn't quite produced the past few weeks. Kirk in games since Zach has had his roll increase but in games still without DeAndre Hopkins, Kirk has a 22% target share 8.2% per game with a team best 31% area share averaging one and a half downfield targets per game which are super high leverage targets. As for Murray we know that the rushing upside is always worth targeting. He's now running for at least 44 yards in four of his past five games, ran nine times in week 17 the second most rushes he's had all season. The Cardinals need a win so this stack should have its foot on the gas pedal until the final buzzer. That'll do it for my favorite NFL stacks, best of luck in week 18. Let's double dip on those touchdown passes on Sunday.
