What evidence do you have that ML would have fired DA? Because to me, that's the height of speculation, making your premise above hypocritical at best.....
The facts that are plain to me are as follows:
1) ML hired DA, kept him around for 3 years, basically changing everything around him and ignoring his awful and obvious shortcomings
2) After last season, he held a PC that could only be described as an absolute clown show, comparing the now arguably worst NFL HC in history to some all time great HC's
3) He defended DA until the bitter end, and his boss (Gayle) had to step in to do the right thing and fire DA
And speculation, ML has an enormous ego and was dead set on proving that he was as responsible for the Saints success during the CSP era.....as CSP was.....
