Witt needs time to develop - yes.
Can we afford to wait? No. Put him beside a decent, experienced playmaker and let him learn the craft properly. Dykes is the perfect choice, but has Smith used them together this year? Maybe once from memory.
It's not what either Witt or Parramatta need.
Tate would be welcome, but I bet he'll stay.
Franze? Dunno about him. He isn't in the Vagana class.
