Congratulations! If you're reading this, the chances are you made your playoffs. That is no easy task, grinding through the toughest part of the game. You've put together an IDP roster worthy of contending for the ultimate glory, whether that be cash or smack talk with those you love to beat. These next two weeks come down to luck and research. Yes, the luck variable can't be quantified or prepared for, but making educated decisions based on what has happened is exactly how to point luck in your direction. So lock in! The bell is about to ring, and we are in crunch time…

Fortune 5

LB Jack Campbell, Detroit

Jack Campbell has emerged as the biggest riser among IDP players this season, and his dominance shows no signs of slowing. The 25-year-old Detroit Lions linebacker delivered another masterpiece in primetime against the Cowboys, posting 12 total tackles, a sack, and a forced fumble. Those numbers pushed his season totals to 129 tackles, five sacks, and three forced fumbles, putting him on pace to shatter every career high. In dynasty leagues, Campbell is pure gold: young, explosive, and already a tackle magnet with legitimate pass-rush upside. He's the rare every-week set-and-forget LB1 who can single-handedly carry your IDP unit to a championship. If he's on your roster, you already know. If he's not, good luck prying him away.

LB Bobby Wagner, Washington

At 35, Bobby Wagner is living proof that legends don't fade; they just evolve. The Washington linebacker keeps getting older, but his production remains eternally young. Gone are the days of chasing strip-sacks and highlight-reel turnovers; today's Wagner is a ruthless, old-school tackle machine who devours ball-carriers with surgical consistency. Through Week 14, he's piled up 131 tackles, three sacks, and a pair of interceptions, delivering the kind of steady, high-floor LB1 output that wins fantasy championships. In an era obsessed with youth IDP landscape, Wagner is the ultimate exception: a future Hall of Famer still anchoring lineups and carrying teams into the playoffs. Age is just a number; elite production is forever.

DT Jeffery Simmons, Tennessee

Jeffery Simmons is flat-out the best defensive tackle in the NFL, and his IDP stat sheet is screaming it from the rooftops. Over the last two weeks alone, the 28-year-old wrecking ball has racked up 13 tackles, 2.5 sacks, and a defended pass, reminding everyone why he's unblockable in his prime. With Tennessee mired in a lost season, trade rumors are going to rear their ugly heads, and Simmons could be the crown jewel of next spring's market. This might be his final ride in Titans blue, and he's answering the bell with some of the most dominant interior play of his career. Whether he stays or gets shipped to a contender, his elite production is here to stay, and your IDP lineup should lock him in now before the rest of the league catches up.

S Nick Emmanwori, Seattle

Seattle's Nick Emmanwori is igniting the back half of his rookie season, proving the Seahawks' bold trade-up to snag the South Carolina star at No. 35 overall was a masterstroke. After missing the first three games with an ankle injury, the 21-year-old has exploded onto the scene, amassing 53 tackles, 2.5 sacks, nine passes defended, and his first career interception. His game-changing versatility is unmatched: a 6'3", 220-pound force who stuffs runs, swats passes, and even blocked a field goal last week. In Sunday's 37-9 demolition of Atlanta, he became just the second Seahawk ever, and first rookie, to notch a sack, INT, and blocked kick in one game, earning NFC Rookie of the Week honors. Dynasty IDP managers, this diamond is polished and ready. Board the Emmanwori express before it's championship-bound without you.

LB Devin White, Las Vegas

Devin White is rewriting his narrative in Las Vegas, delivering the most prolific statistical season of his six-year NFL career. The 27-year-old former No. 5 overall pick has erupted for 133 tackles through 13 games, his career high, while anchoring the Raiders' defense as the green-dot communicator since Week 1. On his third team in as many years, White has flashed double-digit fantasy points in 12 of 13 outings, proving his nomadic days are behind him. This isn't smoke and mirrors; it's elite production from a sideline-to-sideline missile who feasts on volume snaps. Dynasty IDP managers who doubted him? Consider the lesson learned. White's locked in as a weekly LB1, ready to bulldoze your path to a title run.
