Lovren came over from the same club as Van Dijk, and he looked like a top - level defender at Southampton, but the Saints use a far less aggressive defensive pressing style than Liverpool — one that's mainly
focused on moving the opposition into the least dangerous
areas of the
pitch — so it creates layers
of safety for its defenders.
Regarding baseballs, the problem is that the fovea can
focus on only a very small
area — only about 2 degrees
of the visual field (or an
area smaller than your thumbnail held at arm's length)-- so as a
pitched ball moves closer it can easily slip into your peripheral vision as it becomes larger.
