What I read in a Times interview with Lawes is that he's totally finished with England regardless of injury situation but would consider the Lions in the unlikely event they asked him.
Firstly, hope Farrell and his family will be OK. Robust criticism of Farrell the player is fine, anything else really isn't. He's taken a lot of public abuse since the red plus I've always said that Eng have piled too much on him (and probably allowed him to self-inflict pressure too) with all the on and off field roles he's been asked to perform. Any threats to his wellbeing or involving his family are doubly disgusting.
One door closes, another opens, perhaps permanently (Faz will be 33 in Sep).
At 10 it's Smith or Ford. I'd be inclined to roll the dice with Smith but Ford with a bit more licence to play would be fine too, but not really the long term future - turns 31 during the tournament.
Skipper:
Wild card - Spencer's captaining Bath and is in form. Mitchell went OK in France but unconvinced he's the long term answer.
Otherwise lay down the gauntlet to Itoje. Might backfire, but might be brilliant motivation for him (and help keep him in England).
