I really don't think we care about metrics much at Spurs. At least, not since Paul Mitchell, and Comolli before him.
When I look at Steve Hitchen and the rest of our miserable scouting team, I see the same types of traditional, 'eye-for-a-player' type scouts that Billy Beane ran out of town when he took over the Oakland As in the late 90s. We used to be ahead of the game in terms of the statistical revolution in football with Comolli, Michael Edwards and Paul Mitchell, but they have all gone, and we weem to have regressed into a mid-2000s set up, miles and miles behind everyone else.
Same with our physio team. Where is the innovation? You hear of all these weird new methods to keep player fitness going over the years, from blood spinning to horse placenta, but we are routinely one of the worst teams in the league for injuries every season for 20 years, or so it seems. We don't have a club psychologist, which would do wonders not only for our myriad of players with apparent mental health problems and challenges (from Rose to Dele) but for the losers' meteorology this sorry bunch have in general.
What's frustrating is that Levy once had an eye for talent in the backroom team. But now it seems we've hired chancers top to bottom - the good guys have been routinely poached off us (Comolli, Edwards, Mitchell, Inglethorpe and McDermott from the academy, even Trevor Birch after just six months). Not even by top sides - okay, Edwards and Inglethorpe went to Liverpool, but McDermott went to the fudging FA, as I recall, and Birch to the EFL. Surely we can do better in keeping our staff?
However, that nobody wants to poach Steve Hitchen off of us is to our detriment, tbh.
