I’m a big believer in that a true number one wide receiver should fit one of these two profiles…
1) A legit deep threat (Hill, Lamb, Wilson)
2) A big target that battles for contested balls (Evans, Metcalf, Adams)
If you don’t fit one of those profiles, you can still be a very high level receiver, but you’re not a true number one. Stefon Diggs was not either of those things anymore. At one point in his prime, he was a deep threat. He is not that and has not been that for the last couple of seasons. He became a top-of-the-line possession receiver. Which is great! And those are certainly needed. But possession WR’s are not number one receivers in my opinion.
It was time for him to go for his actions off the field and his lack of on the field.
