Garrett has had 10 years to produce results. Is the output on the field equal or better than the talent on the roster? If so-- you have a god coach. If it is less-- then your coaching staff is an issue.
This is not a new thought. This has been declared for years. This staff does less with more than any team in the league. Collin is just saying what everybody knows. Everybody except JJ that is.
And that is the issue. JJ's ego. There is a psychological principle called the point of return. In a belief system, it costs an individual less to continue down a chosen course of action-- EVEN IF CONFRONTED WITH FACTS THEY MADE A MISTAKE-- because to admit they were wrong and do what is necessary to go back to where they made the error is too costly. In essence-- it causes too much dissonance to admit a mistake, so people often follow their destructive beliefs and decisions to their destructive conclusions.
That my friends-- is the situation with JJ. He desperately wanted his red headed boy to bring glory back to Dallas. He still believes he is one oil drill plunge away from the gusher and to quit now would be to miss out on a fortune. Therefore-- JJ looks for any silver lining available to defend sticking by Garrett-- despite the evidence in his face. Because to admit he was wrong about Garrett-- would be to admit the obvious. He has failed miserably as a GM for nearly a quarter of a century.
