I think the highlighted parts answer the question. I have given Ryan praise and it is ridiculous to say how many goals we would have conceded without him. He is in the team because CH knows him to be a competent keeper
After about 6 -9 weeks the choice would have been between Duffy Dunk and Ryan but now the choice is between Ryan and Stephens with for me Stephens edging it as he is the one that has really stepped up his game to a new level.
