Hill vs Siemian why is there a debate?

Why the discussion?

Let alone that Siemian took over in a game in which his drives produced 22 points, Taysom has had a concussion which put him out for 3 weeks now.

That sounds like such serious damage that you can’t put him under center nor let him play his ST army knife role.

Iam really concerned about his health status. Never heard of a 3 week concussion
And its not his first either
According to this draft sharks website, this is his first concussion.

Do you have a link that indicates that he has had other concussions?
