Just to reassure everyone, it's not like Brian Brophy is living under bridges desperate for every little role that allows him to buy food. He is the director of TACIT (Theater Arts at Caltech), so this is could be another reason why they didn't call him (I suppose it's a little more difficult to work with someone who already has a full time job...).

By the way, he still puts Measure of Man between the highlights of his career.
I'm not fond of Maddox' fate in Picard. So I'm fine with the recast of the role, which didn't last long anyway.
