I've had enough of your argument. Nobody has ever said that ONE free agent receiver has the ability to lift an entire team up by it's bootstraps alone. Nobody has said that Jarvis ALONE could ever overcome shitty coaching and shitty QB play.
When the season started we had zero experienced, mature receivers on the roster. We had a group of journeyman borderline guys and a few rookie question marks, and that was it, period. Landry gave us at least one proven option and he absolutely was a positive mentor and a positive influence on the entire receiver room, plus he took Calloway under his wing.
You keep saying that teams only need leadership from the QB and position players don't matter when it comes to being leaders. That's complete bullshit. It takes multiple leaders to turn a rotten culture around.
Your argument has blind spots the size of Jupiter in it.
