I heard that many of his teammates described him as cheerful and a jokester in the lockeroom. He has a couple of teammates that have dealt with suicide and tragic death in their immediate family. Dak Prescott to name one. I heard Daryl Johnston talking earlier. He made the point that speculating that CTE is the cause is premature. the cowboys defensive struggles are worse than I can ever remember and Kneeland was not playing well. Last year as a rookie he looked like he had a promising future. very sad.
