Mike Boone lands with the Miami Dolphins after two Broncos seasons, a veteran addition to Miami’s backfield. Boone totaled 255 yards from scrimmage in 17 games across 2021-22, giving the Dolphins another option behind Raheem Mostert and any rookie-reload. Royce Freeman, former Broncos third-round pick, worked out for Miami, having accumulated 1,596 yards from scrimmage and nine touchdowns in three Broncos seasons. Ex-Broncos front updates include Levi Wallace’s release by Jacksonville, Zack Johnson signing with Detroit, Ronnie Perkins working out for Indianapolis, River Cracraft landing with Washington, and Cam Fleming’s workout with the Commanders. Buffalo designated Jalen Virgil and Justin Hollins as waived/injured. Socials and Broncos fan trivia close the piece.

In broader fantasy terms, the Dolphins’ pursuit of Boone and Freeman signals depth optimization rather than an outright RB1 push, while Washington’s River Cracraft adds a potential speed/space option as the team reevaluates receiver roles. The Jaguars’ move with Levi Wallace and the Lions’ acquisition of Zack Johnson emphasize roster shuffles around athletic depth pieces rather than immediate positional shifts. Colts’ interest in Perkins points to a possible late-season edge-wrinkle, and Fleming’s Commanders workout hints at offensive-line depth battles across the league. Bills’ waivers keep a few names fresh on the market as the off-season churn continues.

Alexander Mattison's season-ending neck injury redefines Miami's backfield. De’Von Achane remains the centerpiece, with Jaylen Wright and rookie Ollie Gordon II providing depth behind him. The Dolphins added Aaron Shampklin and Mike Boone to test veteran options, signaling a shift toward experienced relief behind Achane as the starter absorbs a heavier workload. Shampklin, Harvard alum with Steelers ties, brings a quirky path to the league, while Boone offers 72-game, four-team familiarity. In fantasy terms, expect Achane to carry a bigger share, Wright to operate as a solid complementary piece, and Boone/Shampklin to mix in on passing downs and short-yardage as the Dolphins navigate Week 1 and beyond.

The roster churn underscores the volatility of RB depth in the NFL. Mattison’s exit leaves a gap that the Dolphins are filling with veteran experimentation rather than immediate star power. Wright’s role could stabilize as the clear #2, but the true upside resides in Achane’s expanded touches and the team's willingness to lean on him in early-down and goal-line situations. Shampklin’s Harvard arc and Boone’s career resume add intrigue for late-roster bets and weekly DFS pivots while Miami maps a plan to stay balanced without sacrificing explosiveness.

Alexander Mattison’s neck injury in the preseason opener sidelined him for the 2025 season and landed him on injured reserve after surgery in Chicago. He carried eight yards and a touchdown on three rushing attempts before the injury, and Miami had pegged him as the primary power back to pair with De'Von Achane’s speed and Jaylen Wright’s depth. In response, the Dolphins added Mike Boone and Aaron Shampklin to bolster the backfield behind Achane, Gordon II, Wright, and the rest of the group.

Mattison’s exit opens a clear path for Ollie Gordon II, who topped Miami’s rushing ledger in the weekend’s play with 33 yards and a touchdown on eight carries. The sixth-round pick may be thrust into a larger role as the Dolphins navigate a crowded backfield, while Boone and Shampklin provide veteran and special-teams depth. Fantasy managers should monitor Gordon II’s opportunity window as the backfield reconstitutes itself.

Bottom line: Miami’s backfield now leans into a deeper, more committee-like approach, with Gordon II offering upside as the rookie seizes a glow of opportunity. The team’s week-to-week plan will hinge on how the new signings integrate and how Gordon II handles increased exposure behind Achane and Wright.

The Carolina Panthers have seen significant movement as they approach the 2024 NFL season, particularly with their free agency situation following the conclusion of mandatory minicamp. The most notable departure is linebacker Shaq Thompson, who joined the Buffalo Bills after ten seasons in Carolina. With Thompson now off the roster, attention turns to which players remain unsigned and who has chosen to re-sign with the team.

As of now, several Panthers free agents have not yet found new contracts, including running back Mike Boone, wide receiver Deven Thompkins, and tight end Stephen Sullivan. Re-signings have also shaped the roster, with veteran long snapper JJ Jansen and quarterback Andy Dalton both returning, along with key contributors like center Cade Mays and defensive lineman LaBryan Ray. The dynamics of the team’s roster will be crucial as they prepare for the upcoming season.
