O'Shea is a different type of player to Morris, so no, but I don't think it would be necessary anyway.
Hargrave is very quick and has a good record on smaller players and could play on the quicker types.
Harris, Mcdougall and Williams on the bigger guys, Everitt on mediums and Gilbee and Hargrave on smalls. Addison, Wight and even Murphy as injury coverage.
I'm happy with how our backline is shaping up. I also think our rucks/midfield isn't as bad as is being made out.
Our forward line is a shambles.
