Why the Eagles are Not Going to be Good For a While (explained)

In Pennsylvania or let's just say this area alone is filled with Eagles fans obviously. But honestly, after the Super Bowl 51 win (pretty mad about that), Eagles fans have still to this day keep talking about that one Super Bowl win. I feel bad for Eagles fans after losing 3 straight NFC championship games in the early 2000s. Anyways I should stop my ranting and start talking about why the Eagles are not going to be at their full potential for a while. So first off their secondary is probably one of the worst in the league right now due to the fact that they couldn't get Jalen Ramsey and players and fans were going crazy over but honestly. When I was watching the Eagles play the Vikings in that week 6 game every time Kurt Cousins threw the ball up it was almost always to Stephon Diggs for at least 50+ yards and trust me it started getting real ugly when the Vikings just kept scoring. And also Eagle fans make it seem like Carson Wentz (Prince Harry) is the next Dan Marino which he is most definitely not. Also, their wide receivers aren't that good with the injury of DeSean Jackson and so far he hasn't had great stats either. So that my opinion on why the Eagles aren't going to be good for a while so don't make it seem that they're good are anything because they really aren't.
