Robert Walls says the AFL career of former Demon turned Port Adelaide recruit Jack Watts could be over in a couple of years if he doesn’t get harder at the ball.

“Melbourne were happy to get rid of him,” Walls has told Fox Footy. “Why? Because they just felt that under Simon Goodwin, the senior coach, that he just didn’t go as hard, as strong, as committed as they would have liked.”

“That’s why he got dropped early last year, because they just felt that he wasn’t putting in as expected.

“This’ll be interesting because the expectation on Watts with Port will be really high. They won’t want to see him getting easy ball out wide. They’ll expect him to win his own footy.

“His career could be over in two years. I’ve got a real question mark over Jack Watts and Port Adelaide.”
