Fifty years ago McDonald's grandfather Terry arrived from Swan Districts on a three-year adventure that would see him become part of City-South's run to the national club championships.

After losing to Scottsdale in the 1971 NTFA grand final, Terry's Redlegs downed Launceston in the 1972 decider before taking out the state premiership with a six-goal win over the Darrel Baldock-coached Latrobe.

Terry kicked 4.3 and was named best on ground despite being knocked out in the first quarter.

"I went home straight after the game and put myself to bed," he said.

I wouldn't have been allowed back on the ground these days."

After matching it with Carlton, North Adelaide and East Perth in the club championships, Terry spent 1973 at East Devonport under Alan 'Bull' Richardson - a Richmond premiership player and father of Tigers star Matthew.

By the time Terry and wife Lindy returned home to the traditional McDonald farm in Coorow, WA, they had welcomed their first son Darren - Logan's father - with then-City-South captain Darrel Green named godfather.

Half a century on, Logan is set to further the McDonald footballing legacy by being picked up in the first round of December 7's national draft.

"We're all very proud - I think what makes me really pleased with him is the way he presents himself and he's not getting ahead of himself," Terry said.

"We like the way he plays, he's very team orientated and ... he's forever trying to improve himself.

"He's always been keen on his sport and this is what he wants to do so I have no doubt he'll make a success of it."

Having finished his university studies for the year, Logan faces a nervous two weeks until draft night.

Touted as a first round pick since last year, the 193cm key forward has shot even further up the estimations with a stellar season for WAFL outfit Perth.

The 18-year-old catapulted himself into the spotlight after kicking 21 goals in nine games, including six bags of three or more, to help the Demons to their first finals campaign since 1997.

"This year you go from just being a 17-year-old kid to all of a sudden everyone's talking about you," Logan said.

"It's really exciting and all part of the process - if people are talking it's a good thing but I don't read too much into it - I've got good family and friends around me that keep me grounded and I like to think I'm a pretty level-headed kid anyway.

"I don't get too far ahead and I've been working towards getting drafted for a long time so to potentially have it a few weeks away is pretty exciting."

Considered alongside Western Bulldogs academy member Jamarra Ugle-Hagan as the best two forwards in the draft, Logan hopes to finish his AFL career as a one-club player.

As to whether he is more talented than his grandfather, Logan is sure of one thing - he has Terry well covered in height.

"We're pretty different - he was always a small little nugget rover and forward pocket so I don't know where I've got my height from - he certainly doesn't have much of it," Logan said.

"From what I've heard from a lot people is he was a very good player ... he's got a pretty accomplished career and it would have been interesting to see how he went in the VFL at that time if he went down that route.

"He always has heaps of advice and tips for me but he knows I'm getting plenty of messages so he doesn't push that onto me. I always know that he's there if I need him and he's always a great support and someone I'm grateful to have in my life."
