When the Eagles dealt running back Bryce Brown to the Buffalo Bills during the 2014 NFL Draft, the terms of the trade were a little complicated. The conditional pick that the Bills sent to Philadelphia was the conditional pick that Buffalo received from the San Francisco 49ers in the Stevie Johnson trade. At the time, the Eagles could have earned one of three picks:

"The Bills will send a 2015 fourth-round selection to Philadelphia if:

- Stevie Johnson does not meet production-based conditions in San Francisco in 2014.

- Bryce Brown does not meet production-based conditions in Buffalo in 2014.



The Bills will send a 2016 fourth-round selection to Philadelphia if:

- Stevie Johnson does meet production-based conditions in San Francisco in 2014.

- Bryce Brown does not meet production-based conditions in Buffalo in either 2014 or 2015.



The Bills will send a 2016 third-round selection to Philadelphia if:

- Stevie Johnson does meet production-based conditions in San Francisco in 2014.

- Bryce Brown does meet production-based conditions in Buffalo in either 2014 or 2015."

Now that the 2014 season is over, the pick has been revealed: the Eagles will receive the Bills' 2015 fourth-round selection. This means that both Johnson and Brown did not meet production-based conditions in 2014. It's unclear what exact stipulations they failed to achieve.

The trade ended up being a pretty good deal for Philadelphia. The Eagles were well-equipped at running back with the duo of LeSean McCoy and Darren Sproles. Third string rusher Chris Polk managed to score four touchdowns in 46 attempts. Brown wasn't missed. The Eagles got good value for a backup player that was a seventh round pick for them in 2012.

Meanwhile, Buffalo didn't get good mileage out of the former Eagles running back. Brown was a healthy scratch for the first seven games of the Bills' season. When injuries to Fred Jackson and C.J. Spiller forced Brown into action, the 23-year-old failed to impress. He finished the season with 126 rushing yards on 36 attempts (3.5 average) and one fumble that cost the Bills a would-be touchdown.

Another minor aspect of the Brown trade was that the Eagles and Bills swapped seventh round picks. Philadelphia jumped up to No. 224 to take backup nose tackle Beau Allen and Buffalo scooped up offensive tackle Seantrel Henderson at No. 237. Henderson started all 16 games for Buffalo but finished with the third lowest grade of any offensive tackle on Pro Football Focus.

Now that the Eagles have secured Buffalo's fourth rounder, Philadelphia currently owns eight picks heading into the 2015 NFL Draft:
