Regarding the OP, I’m gonna have to wait a while to say that next year’s team is better in any way than last year’s.

I think Newton’s experience as a leader and his calm throughout big moments will be missed. I don’t doubt that Hass can lead, as he’s been in all our big games, but he was always a 6th man.
