The Cleveland Browns defense is not good. It has been quite terrible most of the year especially compared to come of the competition it has played against. None of that is deniable or debatable.
What has been debated, quite strongly, is who or what is the problem. Is it just the bad defensive tackle group? Is it injuries keeping key players out of most games? Is it Joe Woods’ system and decisions? Is it the loss of LB Anthony Walker Jr.?
In the end, like most problems, the answer is probably a combination of many things.
