Most likely bigger clubs buy players who are good at almost everything but not at speed and acceleration. And smaller clubs end up signing just the worst players but who have good acceleration and good speed. This is also concluded with the fact that 95% of Football Manager clubs always have as a priority the signing of players who are under 23 years old precisely because the young ones are faster than the old ones.
