it's not like Ricki bringing him into the team was out of the goodness of his own heart too. He bought him in to do a job, which would help make his job as manager of the Phoenix easier. It was a mutually beneficial decision, and certainly doesn't mean they have to be best friends for life as a result.
Much in the same way as you don't have to only ever say nice things for the rest of your life about your manager at work, if they hired you.
