No? Why players shouldn't keep their head up?
Why shouldn't Wilson be a moron? Your question is a separate issue and a clear deflection to the main issue.
I should look both ways before crossing the street, even if I have the cross signal.
But if someone flies through and hits me, the fact that I "should have kept my head up" is meaningless and doesn't mitigate his culpabiltiy.
But in this case, "keep your head up" is just a buzz phrase from certain fans who like to pretend that they themselves are tough because they like to watch other tough people get their gray matter turned into cinnamon raisin oatmeal.
Talking tough and getting tingles in your leg when someone gets crushed doesn't actually make the guy in the reclining chair tough.
