Geez, you guys are very critical of McDaniel. Maybe he didn't know that Tua was concussed. A player will sometimes "man up" and cover up an injury because of competitiveness or not wanting to let the team down.
Mcdaniel isn't a doc & if the docs checked Tua for concussion and cleared him, then McDaniel is ignorant of the concussion.
Also, Mcdaniel risks losing the players if they see that he values winning more than their health.
I don't know what McDaniel knew when he allowed Tua to play on that Thursday night so maybe he did know. It's possible he did not; that's my point.
