He said a lot of nice things about Carr. Rightfully so. But he was given a point-blank question and an opportunity to say that Carr would be the Saints starting quarterback and he chose not to answer that. Maybe it's for the reasons you mentioned. Or maybe it's because he's unsure about what he wants to do.
In none of my posts regarding this topic, for what it's worth, have I said that he's gone. I just think it's very clear that they're going to explore all options.
