Ideally you want to enlist the services of someone who is excellent at their job who can help bring out the best of you and maximize every ounce of the last remaining vestiges of life within you when you're in the twilight of your career and I don't get the impression that Banks is that person. Steward was very much was that person though.
I hear you, I think SD may have been underrated. But that doesn't explain why GGG's defense looked poor against Rolls. I am a huge GGG fan, but he is getting touched too much.
