I think we've all heard his slurs of late. Glad to hear it's not alcohol related as many have suspected.
Kosar has undergone 15 treatments with Sponaugle, who had him undergo a PET (positron emission tomography) scan to assess the damage to the quarterback's brain. Sponaugle said the majority of Kosar's damage has occurred to the frontal lobe of his brain, affecting his emotions and speech.
Sponaugle compared the trauma Kosar experienced on the football field to that of someone involved in a head-on, car collision.
"Bernie, in effect, put his head through the windshield every Sunday," he said.
While Kosar was receiving treatments last month, he made an appearance on a Cleveland sports talk radio show in which he became emotional and slurred his words. Kosar sounded intoxicated, and some Browns fans surmised he was either drunk or over-medicated.
Kosar said he "wasn't exactly cognizant" of how the appearance came across. Sponaugle, however, wasn't surprised by it after reviewing several scans of Kosar's brain, rattled by years of being hit by defenders and having the back of his helmet s bounced off turf fields in Pittsburgh, Cincinnati and Houston he described as being as hard as "pavement."
