Fitz is too important to continue mentoring Tua. In my opinion. I have not seen any QB try to teach and mentor like that. He is brilliant and too much of an asset to give away. Smart, great at what he does. Tua is not going anywhere. Let him learn from a grizzly vet that is not jealous or afraid to know what is inevitable. He is doing what every QB should do, but most are too insecure to do it.
