In the offseason, Foles returned to the team that drafted him in 2012 and with which he has had his greatest success as a pro. However, he spent last season as Alex Smith's backup in Kansas City and attempted just 55 passes, completing 36 with three touchdowns and one interception. Now, Foles will serve as the primary reserve to Carson Wentz, with Matt McGloin rounding out the depth chart. Barring an injury to Wentz, Foles should not hold much relevance in 2017.

A year removed from the Rams swapping Sam Bradford for Foles, the Rams decided to trade up for the first pick in the 2016 NFL Draft to select quarterback Jared Goff. Foles wound up starting just 11 games for the Rams, posting a horrid seven touchdowns to 10 interceptions over that span. With Goff and Keenum ahead of him on the depth chart, the Rams decided to release Foles. He then inked a deal with the Kansas City Chiefs and has been put in a decent position as the team's top backup quarterback under Andy Reid (who drafted him). However, he's unlikely to see significant playing time unless Alex Smith should suffer an injury.

Following one of the most efficient seasons in NFL history in 2013 (9.12 YPA, 27:2 TD:INT ratio), Foles unsurprisingly regressed last season, though the drop-off was more severe than anticipated. He threw at least one interception in seven of eight games and saw his YPA tumble to 26th in the league, before suffering a season-ending broken collarbone in Week 9. His touchdown percentage was cut in half (4.2 vs. 8.5) and his interception percentage rose more than five times (3.2, 0.6) compared to 2013. The Eagles traded him to the Rams in March, causing his fantasy stock to plummet as he goes from Chip Kelly's fast-paced offense to one that hasn't finished higher than 23rd in total yards since 2006. His primary targets are Kenny Britt, Brian Quick and Jared Cook, a far cry from what he had in Philadelphia. Foles throws a great deep ball with above-average arm strength — 20 completions of 40-plus yards in just 18 starts the last two years — but now he has to prove he can do it without elite deep threats like DeSean Jackson and Jeremy Maclin. Tavon Austin, who did not catch a touchdown pass last season, is the only burner in St. Louis. The Rams likely will rely on their defense and ground game, heavily utilizing the promising Tre Mason, and when he's healthy, first-round pick Todd Gurley.

Fans of Chip Kelly had long told tall tales of his supposedly incomparable innovation as a coach, making him sound like something of a touchdown wizard who could take almost any offense and turn it into one of the best in the league. They were pretty much correct. Even Kelly's most ardent supporters couldn't have foreseen the absurd efficiency of the 2013 Philadelphia passing game, particularly on the part of Foles. One year after throwing for 566 yards (6.4 YPA), three touchdowns and three interceptions as a rookie third-round pick, there wasn't much reason to think Foles would do much when he stepped in for an injured Michael Vick in Week 5. Foles couldn't have been much better, though, throwing just two interceptions in 317 attempts and finishing with a with a spectacular touchdown percentage of 8.5. Despite his reputation as a slower quarterback, he even managed to run for 221 yards and three touchdowns. Although his 2013 numbers probably aren't sustainable, they're impressive to the point that it seems safe to expect more elite production in 2014. The loss of lead receiver DeSean Jackson is softened by the return of Jeremy Maclin from injury and the addition of second-round pick Jordan Matthews, both of whom project as better red-zone threats than Jackson was.

Foles will serve as Michael Vick's top backup and is an injury away from seeing starts in coach Chip Kelly's offense.

A third-round pick out of Arizona, Foles will almost certainly make the Philadelphia roster as the team's third quarterback, but he's unlikely to make a push for the top backup role.
