Not that I take the title of this thread seriously (and yeah I know it was a joke title when it started) but here's some perspective for the keyboard warriors expecting an instant turnaround for us in '24.
Flanagan took over Sharks late in season 2010. In effect, they were 2nd last (3rd last actually but the cheating purple scum had all their points docked). Team record was 7 / 17 - better than the shape Griffin left us in.
In his first full season, 2011, once again they finished 7 / 17. In round 2 they actually beat us, a team in red hot form, flying high after a GF win. But by end of season no discernible improvement, obviously also he's coaching a squad he's mostly inherited.
2012 - they finished 12 / 12. On the up.
It wasn't until 2013 that they started to win more than they lost - 14 / 10. Another 3 years until they turned the porch lights off.
That's how long it can take to turn a neglected football team around. I actually think he'll get us competitive at least a year quicker than the Sharks, but the stats above suggest people are going to need patience.
