Fantasy Football Risers & Fallers: Devy Leagues (Week 12)

Week 12 of the college football season delivered high-stakes matchups, shocking upsets and standout performances from players across the country. In this weekly breakdown, we examine the aftermath of the weekend’s action, spotlighting the biggest devy fantasy football risers and fallers in the college football landscape.

Created by Scott Fish in the 1990s, the devy format is rapidly gaining traction as one of the most exciting formats in fantasy football. Often described as a “dynasty league on steroids,” devy fantasy football allows managers to draft and stash college players well before they declare for the NFL Draft.

The devy format demands deeper research and sharper projections than a traditional dynasty league, but we’re here to help you navigate it every step of the way. Each week, we’ll highlight the most significant value shifts based on NCAA action and what it means moving forward.

When we talk about risers, we’re referring to players whose value has climbed due to strong on-field performance. For fallers, the picture is more complex. Injuries, reduced playing time and other situational factors can all contribute to a drop in perceived value.

Devy Fantasy Football Risers & Fallers

Devy Risers

Kevin Concepcion (WR – Texas A&M)

Kevin “KC” Concepcion has revived his devy stock in 2025 after transferring from NC State, where a quiet sophomore season in a limited offense stalled his early momentum. Now at Texas A&M, the junior wide receiver has emerged as a dynamic weapon, posting 47 catches for 787 yards and eight touchdowns through 10 games.

With Marcel Reed at quarterback and a more aggressive offensive scheme, Concepcion has re-established himself as a vertical and intermediate threat, consistently creating separation and producing after the catch. His versatility and return ability add to his appeal, and his resurgence has pushed him back into the early-round conversation after a stagnant 2024.

While he likely sits a tier below the top 2026 wideouts like Arizona State’s Jordyn Tyson, USC’s Makai Lemon and Ohio State’s Carnell Tate, Concepcion has narrowed the gap and is gaining ground within the next cluster of prospects. His 2025 tape shows improved route pacing, better play strength and renewed confidence, positioning the wide receiver as a potential Day 2 prospect with upside.

Duce Robinson (WR – Florida State)

Florida State’s Duce Robinson has emerged as one of the nation’s premier receivers this season, totaling 947 yards and five touchdowns on 49 catches through 10 games. He leads the ACC in receiving yards and ranks fifth nationally, having topped 100 yards in five separate outings. His most recent came in Week 12 against Virginia Tech, where he posted six catches for 134 yards and a touchdown in Florida State’s 34-14 win.

That performance marked Robinson’s third consecutive 100-yard effort and helped keep the Seminoles’ bowl hopes alive. A former highly-touted tight end recruit, Robinson was recently named one of 13 semi-finalists for the Fred Biletnikoff Award, given annually to the nation’s top college receiver.

At 6-foot-6 and 222 pounds, Robinson blends rare size with fluid route-running and explosive traits. His hybrid skill set mirrors what Oronde Gadsden II has used to thrive at the next level, making Robinson a rising name on NFL draft boards.

Devy Fallers

Justice Haynes (RB – Michigan)

Justice Haynes has reportedly been ruled out for the remainder of the 2025 season after undergoing foot surgery, bringing an early end to a productive junior year in which he rushed for 857 yards and 10 touchdowns on 121 carries. The injury, sustained late in the win over Michigan State in Week 9, is a blow to Michigan’s slim playoff hopes and adds some uncertainty to his offseason timeline.

Although the foot issue could linger, it is not expected to impact Haynes’ long-term draft outlook. He averaged 7.1 yards per carry and recorded six 100-yard games before the injury, flashing improved vision, balance and burst in his first Big Ten season after transferring from Alabama. If his recovery progresses as expected, Haynes should remain a strong Day Two candidate with a well-rounded skill set and plenty of early tape to back it up.

Mason Heintschel (QB – Pittsburgh)

Pittsburgh true freshman Mason Heintschel endured a tough outing in Week 12 against Notre Dame, completing just 16-of-33 passes for 126 yards with zero touchdowns and one interception. His 48.5% completion rate marked a career low, and the Panthers’ offense didn’t reach the end zone until the final play of regulation in a humbling 37-15 defeat.

Even so, Heintschel has shown encouraging signs throughout his debut season, throwing for over 1,600 yards and 12 touchdowns. As a first-year starter in the ACC, he’s displayed the arm talent and poise that point to a bright future ahead.
