Oh, that's all well and good and I'm sure the management would have been delighted to do so, as would we all, but where are we going to get players who will replace what's already there? As I said there's not a queue of them out there waiting for the call.
The alternative to signing Da Vita, Todd etc would have been to keep McLean, Tidser etc, and I've no doubt that you would have been very vocal about M&M's failure to recruit during the window if that had been the case.
I'm not having a go mate but things aren't just as simple as you seem to think.
