Sitting on a 1-3 record, the Philadelphia Eagles have failed to match the preseason hype so far in 2015.
A whole host of theories - from poor play-calling to unnecessary offseason meddling, or simply individual errors - have been put forward to explain the franchise's poor start to the season.
But none has been quite as bizarre as the suggestion made by personal trainer/writer Andrew Hurst who has identified Sam Bradford's behind as one of the major issues for the Eagles.

Hurst, a personal trainer who works with former NFL player Brian Baldinger, argues that the Philly quarterback's lack of 'butt strength' is holding Bradford and his team back.
Citing strong glute muscles as an essential requirement for an efficient and effective throwing mechanism, Hurst lamented the fact that the Eagles have put the short-term need to have Bradford on the field ahead of long-term progress.
So, what's the solution for Bradford and his derrière?
"Sam needs to add about 20 pounds of butt strength and lat density," wrote Hurst.
"The team is physiologically incapable of practicing perfectly right now, and it is showing."
Early season issues
Bradford produced his best game in an Eagles jersey last weekend against the Redskins, but he has drawn criticism this season for his lack of accuracy and deep-ball throwing.
The former Rams star ranks 28th in completion percentages amongst NFL quarterbacks this year and a lowly 25th in yards-per-attempt.
With increased glute strength supposedly creating a strong base for accurate throwing, perhaps a few more hours in the Eagles' gym facilities, rather than out on the practice field may be the key to turning around Philadelphia's season.
