MELBOURNE debutant Jack Viney has spoken to the Demons' playing group after the embarrassing 79-point thumping at the hands of Port Adelaide on Sunday.

The players were locked away in a meeting following the final siren, and didn't re-appear for almost half an hour.

After co-captain Jack Grimes addressed his teammates, Viney was one of several Demons who spoke after the demoralising defeat.

With the club desperately trying to find an answer for the insipid performance, it was the first-gamer who took charge in the change rooms after earlier being one of the few Demons to impress on the field.

"Jack spoke to the players. He's got a mature head on his shoulders and he acquitted himself well on his AFL debut," coach Mark Neeld said on Sunday.

"The players got to hear from Jack a little bit.

"He is - if it's possible when you play your first game - he's probably been a Melbourne person for longer than anyone else in that room.

"He just spoke about that, which is from his heart."

Viney and fellow debutant Matt Jones each racked up 22 possessions (16 contested), and provided supporters with glimpses of what's to come.

The young tyro also had six clearances, kicked a goal and finished with 86 Dream Team points.

Along with captain Jack Grimes, the trio was a shining light for a club that has plunged into darkness.

"We probably had three acceptable performances on the day and two of them came from debutants," Neeld said.

"It's hard to see a team positive in that."

Port Adelaide coach Ken Hinkley admitted to being concerned about the impact Viney was having in his first match.

"We were really concerned about Jack Viney at half-time, and we go 'gee, he's a first year player,' but then our first year players are out there doing some pretty good things as well," he said.
