I've always wanted more patience with Walker at 5/8 by allowing that skillset to flourish in a limited way in the centres(as an option play similar to J.Lyon) then move him back.
You can see Walker has potential but trying to live up to it in a weak squad that was continuously changing was too much pressure on his shoulders to perform.
Now with stronger go forward, time and space and under a top class coach Walker can slowly grow into the role either from centre or the occasional move to 5/8 like today----Dessie might stick with Walker at 5/8 as he adds sharpness in that channel when we are rolling teams backwards.
Cust is ok, cheeky but lacking the kind of pace that can hurt teams in the warmer months of Semi final time, Croker is direct but lacks class and is tough.
