The problem I have with this analysis is we have gone from several "knowns" to several "unknowns". The scenario you lay out of getting replacements sounds good, but we have an awful lot of holes to fill now, and no guarantee that the replacements we get will be comparable in quality.
I would also say, until proven otherwise, we are a lot weaker at corner. I don't know how anyone could feel confident in Youboty stepping up into a starting role given his (non-)performance last year.
