KG has made a big call on Adelaide skipper Taylor Walker, saying it might be worthwhile for him to go back to the SANFL to get "things right".
On Triple M Adelaide's Dead Set Legends on Saturday morning, KG wasn't happy with the big Texan's physicality against Geelong.
"I love this bloke, (but) I saw our captain not involved in any physical contests at all," he said.
"That's the part that disappointed me. At no stage of that game did Tex try to intimidate any players or knock a player over."
He looked at Geelong skipper Joel Selwood, who earned plenty of praise for his best on ground performance despite being split open in the first quarter.
"That's a leader. That's the way to show the players you're fair dinkum about the contest," he said.
He also made a big call: maybe Tex should go back to the reserves and figure that out.
"I just wonder also whether it's time Tex went back to the SANFL and got things right.
"I'll probably get shot for saying what I've said!"
