Two sided coin, McInnes has brought in the sports science. It didn't exist before he arrived and if we are to blame him for the current injury crises should we also complement him on this never having occurred before over his 6 years in charge?
I think the point made above is a good one. There are reasons to be unhappy with some of the things McInnes is doing but blaming him for the injury crises is just being unreasonable.
