For Newcastle, 100% definitely 2002. Definitely would've won the premiership until Johns got injured in the Qualifying Final. That would closely be followed by 2000, which I have mentioned in one of the threads on the Knights forum. 3rd would by 1998. Had a chance, were neck and neck with the Broncos (only to be edged out of minor premiership on for and against), but blundering after leading 15-0 and 16-0 against the Roosters and Bulldogs respectively (in the finals) pretty much sealed our fate.
Those would be the only 3 years where on a scale from 0-10 (after qualifying for the finals, 10 being absolute certainties to win the premiership and 0 meaning virtually bowing out in Week 1), we were rated at least an 9/10. 2002=10/10, 2000=9.5/10, 1998=9/10
