Going into it, I thought it was going to be a commercial for the NFL, which I love, but it was not. Keep in mind, especially in the NFL, the game is much safer, and I am all for the restrictions that they have implemented. These kids ARE heroes and they deserve all the support that they can get. If you want to see a drama about CTE in the NFL, see "Concussion" (2015) starring Will Smith, who I thought deserved the Oscar that year for his portrayal of Dr. Bennet Omalu. Dr. Omalu is the person who discovered CTE in NFL players.
I STRONGLY recommend both films!!
