The most interesting takeaway from the New York Jets’ Wednesday media availability pertained to the physique of third-year running back Braelon Allen.

The Wisconsin product revealed that he is up to 250 pounds after weighing in at 238-240 going into the 2025 season.

On paper, it’s the type of development that can get fans excited in the month of June. It’s easy to picture a 250-pound running back plowing through Bills and Patriots defenders in December.

But is this the right move for Allen’s game?

Examining the possible effects of Allen’s weight gain

The 2024 fourth-round pick has struggled to stand out through two NFL seasons. Across 17 games in his rookie year, Allen averaged just 3.6 yards per rush attempt on 92 carries, ranking 44th out of 47 qualified running backs. He scored three total touchdowns, but two of those came in Week 2.

Allen’s second season was cut short due to an MCL sprain in Week 4. Before the injury, he was up to 4.2 yards per carry on just 18 attempts, but he lost a crucial fumble near the goal line during the game in which he was injured.

Entering 2026, Allen is averaging just 3.7 yards per carry in his career, with four total touchdowns and one fumble in 21 games. It’s not the best resume for a projected No. 2 running back in a league where teams are becoming increasingly reliant on rotations in the backfield.

Although Breece Hall is locked up for the future, the Jets will count on Allen to spell him for multiple series per game, and he will be the next man up if Hall goes down. Allen needs a big year in 2026 to prove he is worthy of those responsibilities.

Given the holes in his game thus far, it is fair to wonder if a 10-pound increase to his already massive frame is what Allen needed.

Breakaway speed has been a significant limitation in Allen’s game. On 131 career touches (rushing and receiving), Allen’s longest play went for just 20 yards.

Now, Allen will step onto the field with an even bulkier frame than before.

To be fair, Allen stated in his interview that his body fat percentage is its lowest ever, so it’s not as if he is carrying dead weight. Nonetheless, a 250-pound running back is a 250-pound running back. There’s a reason you don’t see too many of them; speed and quickness are paramount at this position, and it’s difficult to have those traits at an NFL-caliber level with that much weight on your frame (unless you’re Derrick Henry).

In a league where defenses have gotten smaller and quicker over the years, Allen is now heavier than many of the off-ball linebackers who will try to tackle him. Will he have enough speed and quickness to outrun them, especially since he already struggled to gain open-field yardage at a much smaller frame over his first two seasons?

The Jets’ hope is that Allen’s enormous frame and unique power will allow him to make up for the speed and quickness deficiencies by plowing over defenders. But if that were such an easy thing to do based on weight, then we would see 250-pound running backs all over the NFL. Being big doesn’t automatically make you an effective running back.

Perhaps the Jets are preparing to use Allen in a specialized role, looking to have him dominate in short-yardage. He certainly has the potential to dominate in that role, and if he does so, his bulk-up could be valuable. It’s a weapon to have a player who converts third-and-1, fourth-and-1, and goal-line carries at a high clip.

But if that becomes the only situation in which Allen is effective, is it worth it to sacrifice the rest of his game? Ultimately, many of those short-yardage plays come down to the blocking, anyway. There is only so much a running back can do to control his short-yardage efficiency, regardless of his frame.

On plays outside of short-yardage, Allen might be rendered ineffective at 250 pounds. You need your running backs to occasionally sprinkle in breakaway runs to maintain high efficiency in terms of yards per carry, or even metrics like EPA (Expected Points Added). If Allen stockpiles carries without hitting home runs, it will hurt the Jets in the long run, as the average running back would hit far more dingers with the same diet of carries.

However, Allen could be a positive early-down back without breakaway speed if he maintains a high success rate. Even if he rarely goes for 15-20-plus yards, he can be a positive difference-maker by consistently picking up at least 4 yards. Those carries keep an offense ahead of the chains, even if the runner is brought down after getting through the first level.

Allen did this decently well in his rookie year. His 51.1% rushing success rate ranked 18th out of 47 qualified running backs, per Pro Football Reference, a much higher placement than his No. 44 slot in yards per carry. It shows that Allen typically kept the Jets offense in favorable spots, even if his overall yardage output was poor.

If Allen can keep that up, or even improve upon it, his bulk-up could be a positive for the Jets. It would be beneficial to have a short-yardage battering ram who can also reliably chain positive gains on the early downs.

Those goals are easier said than done, though. If more weight equaled a higher chance of scoring a goal-line rushing touchdown or converting a short-yardage carry, every team would be running Sheldon Richardson-esque plays with their defensive tackles. If it were easy to find a 250-pound running back who could bowl his way to 4 yards at a high rate, we’d see every team with one of them.

It’s up to Allen to learn how to carry his unusual frame with the necessary skill and finesse. If his game solely relies on putting his head down and bowling over defenders, he will probably struggle to be effective. He still needs to couple his power with excellent vision and at least adequate quickness to become efficient enough in short-yardage and consistent enough in early-down success rate to justify stockpiling a large number of carries without being a home-run threat.

The Jets have made an ambitious player-development decision with one of their youngest offensive weapons. Let’s see if it pays off.
