I definitely think 3 years is a workable time frame
0 - 3 months First rumblings from the feral supporters, game plan is crap theme, this bloke doesn't know what he is doing....
6 months Media latches on and joins the "tigers are crap" theme
Growing army of the ferals gets louder
1 year Rumours of board coups start to surface
Coterie groups start becoming more vocal in their "bring back the good old days"
1.5 years Coach under pessure from media and supporters to guarentee date when we will play finals
2 years Board backs coach 100%
2.2 years Coach sacked caretaker Wayne Campbell appointed
2.4 years Calls from media, coterie groups, supporters to appoint Sheedy
3 years New coach appointed
Yep 3 years should be enough to fit all that in.
