Without knowing the inner workings of Managers like Sir Alex Ferguson, I would have to say yes. Yes us Data people would be better at managing football sides. After all I do really well at football manager simulation games like Football Manager (well named yes) so obviously I could also take out the Premier League in real life too.
In reality I think I think it takes a combination of game smarts and a realisation of what teams/players are/can do via data. Relying on either one too much could lead to failure.
