He'd be a Hall of Famer if he were a Warriors coach with that record.
But seriously, making the finals nearly half the time, a GF that they could've won on another day, then a pair of finals wins in 2020 isn't a bad effort at all for a non-Sydney club that can struggle to attract the top talent. Yeah, his record at the Sharks and Eels was shithouse but holy shit, as I say, if you give me his 8 years at the Warriors I would pay you significant amounts of money - and I'd say Raiders fans might feel the same.
