Picture a standings board for the NFC East over the last twenty seasons: four different names at the top, no repeat since 2004. That's not a throne, it's a carousel.
Incumbent isn't ruler. My opponent's belt point is fair, but defending a title isn't sustained control.
The standard is contested. If the gap is thin and the next challenger is close, the benchmark shifts yearly. Close doesn't mean overtaken, true, but ruling needs separation.
Repeat test. Until someone wins it twice or dominates head to head, nobody rules. The Eagles are latest, not permanent.
Bottom line: latest winner, not ruler.
