The worry I have with a combination of Gawn and Grundy is that it'll give the Demons options to rest both at different stages throughout the season for minor niggles or to freshen up later in the year.
That is a legit worry, surely they both don't play every game together?
In 2012 Cox (30yo, $662.6k) went 112.3 from 22 games. Naitanui (21yo, $508.8k) went 114.2 from 20 games.
The two games Naitanui missed were Rds 6 and 7 with hamstring tightness (he was named for Rd 6 but was a late out).
He carried a groin complaint through the tail end of the season during which period he posted 3 of his top 4 highest scores of the season (164, 163, 153). After West Coast were knocked out in the semis he had groin surgery.
In terms of structure, one would be named in the ruck and the other in a forward pocket alongside JJK or on the bench. JJK did his ankle in Round 5, so thereafter FF and CHF were shared between Lynch and Darling with Cox/Naitanui resting in the pocket.
1062 hitouts and 48 goals 26 between them. West Coast finished 5th with 15 wins. They went alright in the finals too, 148/125 (Cox mentioned first) against Goldstein/Petrie in a demolition of North at Subiaco and 98/91 against Jolly in a tight loss to Collingwood at the MCG.
Anyway. That's all ancient history now. Julia Gillard was PM for Christ's sake.
