Because if Blore gets injured as some keep suggesting that he might, we then have Doueihi and Blore burning 2 top 30 spots for the year or at least possibly a good part of part of it and we haven't gained any depth in the centre position where we currently have no depth.
It can be argued that we do not currently have depth in the second row position which is where the opportunity comes in for the young up and comers and I believe Blore's best position was really going to be in the middle where it could be argued that it is a position that we have our greatest depth in already.
Yes you are quite right in questioning Olam's motivation, but if he came here on loan for a year with us having an option for the remaining 2 years of his contract then the majority of the risk would fall on the Storm rather than us and this would especially be the case if we were only paying Blore's contract value plus maybe a little sweetener thrown in.
With regards to Olam's motivation, and I could be wrong, but I see him as being an honest and honourable type of person and I don't see him tanking and not putting in a full effort in an attempt to redeem himself and if he performs poorly then it is because he is in fact past it.
Like I have already said the majority of the risk would be with the Storm and I don't really expect a deal like this to come off, but it is the kind of thing we should be looking at more often rather than coming off 2nd best as we often do.
