Nick Foles: This is an obvious one. Nick Foles had some hobby love during his original run with the Eagles, when he had one of the best statistical seasons ever for a QB. His performance this season after Carson Wentz's injury is sure to re-ignite the value of his cards. Expect to see some increase in value right now, and if he decides to explore the free agency market for a starting position, you can expect his (potential) new fan base to continue to drive the value before the season.
Corey Clement: If you were following the Eagles this season, you already saw the glimmers of star power throughout the season. An undrafted rookie this year, Corey stepped his game up at a critical point for the Eagles, and delivered a phenomenal Super Bowl game. Midway through the game, I logged onto COMC and noticed that he barely had any cards listed - so someone swooped them up earlier in the game or during this week. Jay Ajayi and Legarrette Blount have been the bigger names, but don't be surprised if Corey gets a chance to continue to blossom on this team next year.
Carson Wentz: The logical path forward for the Eagles is to return to Carson Wentz as their starting quarterback this year. The team really never lost a step after Wentz went down with his injury, so you could argue that the team would have likely had the same outcome if Wentz had played the remainder of the games. Regardless, he is the future of the franchise and I don't think anyone will believe that Nick Foles is their starting QB next year. Invest now while his prices may be low due to the injury, because the team has just show that they are capable of winning a Super Bowl and will have an even better chance of repeating with a full season of Carson Wentz next year.
