re: How long will the starting LT and RT be out?

The direction of impact can affect the severity. But just like some people get over the flu in 1 day and others 7, the individual is going to be the biggest factor.

From what I understand, side impact is worse because of potentially compressing the hemispheres and 'more room to slosh around', but we're way out of my wheelhouse here.

I'm only going on what a doc told me back in the day when I had one. And that was way before a lot of studies... and really, how much can a concussed man understand of what a doctor is telling him.
