I think the Eagles are good because they won 9 games last year with a slug at QB. They went into the offseason and upgraded some key holes on their team - WR, pass rush, CB. They have an easy schedule again. Hurts likely can't be worse than he was last year, when again, they won 9 games with him. It's not just about what they have done in two weeks, it about looking at their team overall. They are very good in the trenches, especially along the OL.
It's just common sense at this point to see that the Eagles are actually not some fraud joke here but actually a good team. That doesn't mean I think they are about to go 17-0 and win a SB here either. They just are a good, talented football team. That's just the reality that you are struggling with accepting.
