If Begs plays the AFL in Rd.1, we'd be looking at dropping Myers i imagine.
Reckon we're looking at a starting 22 of:
Gleeson - 2 of Hartley/Ambrose/Bags/Francis
Saad - Hurley - McKenna
Parish - Heppell - Merrett
Stringer - Daniher - Tippa
Fantasia - Hooker - Stewart
TBC - Zaka - Smith
McGrath - Goddard - ?? - ??
2 spots for Myers, Colyer, Laverde, Langford, Begley
I reckon you've nailed the core of the team + the spots up for grabs. The only player i'd add as a potential would be Mutch but at this stage he is still behind those others you listed. Langford I think will be a lock at the start and given a chance to prove he deserves it.
Backline is interesting - do we drop Bags or do we go with just 2 talls which will leave us pretty exposed against taller forward lines. In fact considering we are playing Adelaide - I can't imagine that we would only play 2 talls in round 1. I'd be surprised if Ambrose was left out. A genuine shutdown player that can play on different types is needed when you look at the rest of our defense which is pretty attacking.
