Two led to tries and there was a poor tackle on Crichton (snaps from highlights)Slater was being kind.
Walsh was out of position the entire game, not just once.
Last one Walsh has been tracking the ball the whole time from (his) left to right and gets to Crichton and tackles so high. He literally bumps off Critta.
The only try that I recall where he creates one is for Mam's 3rd try where he steps Cleary and fends off Tago and passes to Mam.
I am sure if you watch the entire game there will be lots that Walsh is doing wrong.
