The Carson Wentz wagon is reaching capacity ... 'cause yet another Eagles superfan is hoppin' on board ... with Sly Stallone saying the rookie QB can lead Philly to a Super Bowl THIS YEAR!!

The Eagles are on a bye week ... but then they've got the Lions, Redskins, Vikings and Cowboys.
Meanwhile, Jared Goff hasn't played a snap ...
