I 100% agree with what you're saying, but I also think it's fair to say that they've both improved massively on their weaknesses. Both have been getting a few turnovers, which last year, or maybe even last month, would've been unimaginable. And whereas Haskell used to just be a lump, his work rate is now superhuman, the same goes for Robshaw, but his work rate's always been great. I think it's fair to say now that if both keep up the form they've found under Jones, both are serious contenders for spots in the Lions squad.
They have always gotten the odd turnover. But yes they've both improved massively and it seems EJ has made them own who they are as 6.5s and just go out and play. Lions wise Haskell would make living with the lions more interesting but with falatau, heaslip, vunipola, etc there is a lot of competition there.
