Danny Kanell believes there is a war on football due to concerns about Chronic Traumatic Encephalopathy. 

Kanell is a college football analyst and radio host who played quarterback at Florida State and in the NFL for six seasons.

"The war on football is real," wrote Kanell. "Not sure source but concussion alarmists are loving it. Liberal media loves it. Doesn't matter. It's real."

Kanell was referencing this New York Times op-ed by Dr. Bennet Omalu, who writes that children shouldn't be allowed to play football because research shows that "it has become clear that repetitive blows to the head in high-impact contact sports ... place athletes at risk of permanent brain damage."
