The trade winds in the NFL keep blowing. There’s been no stopping them over the last week, and two quarterbacks were swept up in the minutes before free agency officially opened today. The Philadelphia Eagles and St. Louis Rams have agreed to trade reports. There will also be some draft pick compensation, but the exact picks to be exchanged is still unknown.

Both teams needed to upgrade at quarterback this season, and settled on choosing the quarterback the other team wanted to upgrade from. There’s some logic involved for both sides of this trade, though, so let’s look at why this trade happened from each side.

For the Rams

Trading Bradford saves about $9 million of cap space in 2015. The trade will leave $3.595 million worth of dead money on St. Louis’ cap, but that is well below the $12.985 million Bradford was to count for this season. The cap relief is certainly nice, but the player they are getting in return is mostly a less-expensive option of what they had.

Most will remember Nick Foles from his stellar 2013, leading the Eagles to the playoffs after stepping in for an injured appear to be less correct. As of this writing, nothing has become official yet, but this may be the most important part of the deal. It has been reported that the Eagles will receive a conditional pick in 2016. As the other compensation, the conditions have not been announced.

If the Eagles get to move up in the draft at all for swapping players who more than likely won't make a huge impact, that could tip the scales to Philadelphia’s favor. Each move up in the draft potentially brings the Eagles a step closer to a trade for Mariota. If that’s the endgame, the Eagles may be on to something. If this is just a swap of quarterbacks, not much on the field has changed.
