He may not make it but I think we need to remember that a player called D.Martin did the same thing by turning up unfit to preseason training early in his career.Apparently Stacky has a pre season fitness clause in his contract that financially rewards him for turning up in good condition ( which means he meets certain benchmarks) .
If that hasn’t motivated him, he probably won’t make it
Reckon some are over reacting with Stack's current condition.
Stack began last pre season in similar poor form, but gained conditioning during the pre season.
I've watched the rd1 game vs Carlton a couple of times and Stack looked fit and sharp, and was ready to take on 2020. Then COVID hit and his form dropped away considerably.
He's young and at this stage of his career his conditioning seems to drop away quickly when he's off the track and it takes him a while to gain it back. The gap will shorten with more preseasons and experience. Got faith in our conditioning guys to sort out Sydney's fitness.
