Think that’s a bit harsh on Porter, don’t think he did a lot wrong apart from a few long box kicks.
Not sure Robson added anything and made a few costly mistakes himself
Will was slow arriving at a few breakdowns, which affected momentum since everyone just waited for him. Getting players to effect quick clearout (we're not that good at it) and swift distribution (Dobby was woefully slow last season) is key to good attacking approach as it sucks in defensive cover, when done at pace, leading to gaps from which scores are created.
I think Wasps fundamental issue is our inability to create quick ball at breakdowns when we have the ball. That's leading to us trying to do it in open play with Hail Mary offloads, snatched passes and loss of composure. That is definitely a coaching failure.
When we do it well, such as Crossdale clear out for Brad's try last week, we scored.
Another issue is when we're close to the opposition try line we use 1 out runners to try to batter through and they are inevitably stopped. After lots of phases getting nowhere we then try a backs move under pressure and lose the ball. That's another coaching failure.
We should try using a support runner who can either drive the carrier or smuggle the ball and either swivel round the corner through a gap or offload to a player running round behind to exploit space out wide.
