The Brighton camp is for probably for Eddie to look at other talent that he may not have seen before or for a long time. You’ll probably find the next squad (Autumn internationals) Cipriani again.
I did initially find it odd however, that if Cipriani is being judged on his rugby, how Ashton ever made it in that squad when he is currently banned/not playing and that was an on field incident. But then I came to the assumption mentioned in my first paragraph.
