If you had a choice between GWS and Port Power's list as an incoming senior coach, you would easily choose GWS.
Ports main concern is ageing. Port need to retire the 30y+ Boak, Gray, Motlop, Mckenzie and Dixon. They don't need an entire list change over like the Crows did but the the amount of over 30s and very late 20s in the side is starving development opportunities. The only one id keep for an extra year is Jonas.
Below them that will be 27 plus next year are Aliir, Amon, Byrne-Jones, Clurey, Dumont, Fantasia, Finlayson, Lycett, Mayes and Wines.
Over 25y will be Bonner, Burton, Houston, Powell-Pepper, Skinner.
That is an incredibly old list. Thats 3 waves of players who if ports not careful will play too long together and get old at once.
GWS
Over 30s Davis, De Boer, Keeffe, Lloyd, Ward (not as reliant on the old men as Port are)
Over 27s Coniglio, Greene, Haynes, Hogan, Kelly, Kennedy, Pruess, Stein, Whitfield (the stars of the side are still all under 30)
Over 25s Buckley, Flynn, Himmelberg, Hopper, Taranto
Massive difference in squad balance.
Overall a coach looking to build into a successful era and push finals would pick GWS. Port is a sinking ship and you'd be spending the next two years developing and drafting.
The famous catch cry of a destination club by Port has seriously hurt them. Worst decision they made was take Motlop. How that lazy individual gets games is anyones guess.
