Yes, it looks like he has been following DL very closely. He presents some very well thought out arguments, and his stats on the Hawks goalkicking, scoring shots and accuracy are something that the rest of the footy media have overlooked.
The comments on the retiring players, and the age of the rest of the squad seem to indicate not that the "Premiership window" is closing rapidly, but that the best is still to come. IF Freo get McCarthy, Bennell and/ or a couple of similar players then his prediction could be on the money.
