There are no scenarios in which Philly will get a 3rd from the Bills in 2015. If the 2015 4th Round pick for Stevie from the 49ers turns into a 3rd, the Bills keep the pick. Here's what can happen:
- If neither SJ nor Bryce Brown reach set production levels with their new teams in 2014, Philly gets the 2015 4th Rounder.
- If SJ does reach set production levels with SF in '14 & BB doesn't reach his with the Bills in either '14 or '15, the Bills send Philly a 4th in 2016.
- If SJ does reach set production levels with SF in '14 & BB also reaches his with the Bills in either '14 or '15, the Bills send Philly a 3rd in 2016.

In any event, a 4th in either 2015 or 2016 or a 3rd in 2016 is not a high price to pay for a RB with Bryce Brown's talent. He was a beast in the games he filled in for the injured LeSean McCoy. As others have stated, he's young, talented, & will be a valuable insurance policy for Freddie. The Bills have assembled a dynamic RB & WR corps. This was an excellent trade, IMHO.
