My ex-roommate and very close friend is a physio for one of the URC rugby teams, i.e. one of the biggest rugby union franchises in the world. He is an expert in knee injuries and we routinely talk about how they come about in football because ligament damage is generally ubiquitous in rugby whereas it's a sporadic injury in football owing to the different levels of physicality etc. One of his major bugbears is conditioning, he says professional footballers are over-conditioned compared to a lot of other team sport athletes, particularly in preseason, and this is why so many season-long injuries occur earlier rather than later in seasons.
So that's where I'm getting my fixation on our strength & conditioning coaches from, it's not just idle speculation, but even if it were, doesn't take a genius to think we should take a look at our regimen and make sure it's fit for purpose.
