The 2027 NFL Draft has obvious headliners. Arch Manning, Dante Moore, Jeremiah Smith and several elite edge rushers will dominate early mock drafts. September, however, is when less established prospects force scouts to rewrite their notes.

A transfer can fit a better scheme. A former backup can turn 10 touches into 20. A defender returning from injury can remind evaluators why he once carried an early-round grade. That is the kind of September stock surge worth tracking.

Readers checking the top 10 betting sites for Heisman or college football futures should pay attention. Draft risers often become award candidates before the market catches up. WalterFootball’s 2027 prospect rankings provide the wider picture, but these seven players have clear paths to a fast start.

Trinidad Chambliss, QB, Ole Miss

Chambliss lacks prototype size, and his age will be discussed throughout the process. None of that changes the problems he creates with dual-threat pressure. He is quick enough to punish man coverage and dangerous when the play breaks down.

Scouts will study his pre-snap identification, timing against disguised coverage and willingness to take easy completions. If those areas improve, Chambliss can become a legitimate Day 2 option. Two or three efficient September performances could transform his outlook.

Justice Haynes, RB, Georgia Tech

Haynes averaged 7.1 yards per carry at Michigan in 2025 before a foot injury interrupted his season. At Georgia Tech, he should receive enough work to display his NFL-caliber acceleration rather than leaving evaluators to project it from limited touches.

Haynes can press the line, make one decisive cut and reach the secondary quickly. He has also shown receiving ability. Durability remains a concern, but a healthy month filled with explosive runs could push him toward the top of the running back class.

Lance Heard, OT, Kentucky

Offensive linemen rarely create viral highlights, but Heard may not need them. The 6-foot-6, 325-pound transfer has blind-side anchor potential and enough movement ability to become more than a massive pass protector.

Scouts will focus on his balance against speed, hand placement and recovery when initially beaten. If his technique looks cleaner, he can climb quickly because dependable tackles remain scarce. Strong September tape could establish Heard as a first-round possibility.

Lawson Luckie, TE, Georgia

Luckie caught only 15 passes in 2025, but four went for touchdowns. With Oscar Delp gone, Luckie finally has an expanded receiving role in an offense that regularly sends tight ends to the NFL.

He is a natural target between the numbers and has enough size for the red zone. The key is proving he can stay on the field as a blocker. If Georgia features him early, his production could rise sharply. The top 10 betting sites may notice his touchdown totals before casual draft followers notice his route running.

Antwan Peek Jr., LB/S, Cincinnati

Peek is the type of defender who creates arguments in draft rooms. At roughly 220 pounds, is he a safety, nickel linebacker or subpackage player without a permanent position?

His best selling point is positionless defensive value. Peek can cover, tackle, blitz and create turnovers, including six forced fumbles over the past two seasons. NFL teams will want to see where he lines up on important downs. A defined role with regular splash plays could make him one of the class’s fastest risers.

Tony Rojas, LB, Penn State

Rojas was producing at a high level before a torn ACL ended his 2025 season after four games. His first task is looking like a healthy three-down linebacker again.

Before the injury, Rojas showed range, closing burst and playmaking ability in coverage. September will test his confidence when changing direction, taking on blocks and pursuing outside runs. Scouts are cautious with players returning from knee injuries, but natural movement can erase that concern quickly.

Duce Robinson, WR, Florida State

Robinson is not an unknown after recording 1,081 yards in 2025, but he has room for a major stock jump. At 6-foot-6 and around 230 pounds, he owns a rare catch-radius advantage few defensive backs can match.

Now scouts need refinement. Can Robinson separate against press coverage, sink his hips on intermediate routes and win when defenders remove the easy vertical release? Improved technique, not simply another large stat line, could move him into the first-round conversation.

September Matters More Than the Box Score

The opening month will not complete any evaluation, but it will decide which players receive serious attention once conference play intensifies. Production matters; early-season film showing better processing, healthy movement or a larger role matters more.

The latest 2027 NFL Mock Draft will begin to shift as soon as the season gets underway. The same is true of the futures market, where the top 10 betting sites for those in the UK are likely to react quickly to early breakout performances and changing award odds. Chambliss and Haynes have the clearest paths to immediate statistical success, while Heard, Peek and Rojas may generate even more interest among scouts than they do in weekly highlight reels.

September always produces a few misleading reactions, but it also reveals which prospects have genuinely improved. These seven players have the opportunity, talent and expanded roles needed to turn a strong opening month into a major rise up draft boards.
