Bellamy & Gus I have in the GOAT class
Ivan a rung below at this stage, if he can keep us top 4 for the next 5 or 6 years then he is alongside Bellamy, extra premierships gets him ahead. Cant bench him against Gus, will never get the chance to have the same rep opportunities. Took Warriors to a GF, and also only missed finals twice, once because of points deduction for a cap breach and the other the year Sonny Fai died. Tiges to ninth with Brooks getting HB of the year, the dud signings have been a Tigers thing well before Ivan and have continued since, so can't take much from that. I think people underestimate how truly shit we were when he arrived for stint one. Got us to a prelim in year 3 off the back of players he developed plus Soward & Merrin, all with a horrific injury toll. Sent for a nap after missing the finals with an even more horrific injury toll. Stint 2 speaks for itself.
Skeletor is a bit of a myth. Obviously can coach, but has been kissed on the dick by a fairy with the tool set he was handed. Still pretty much let the GOAT Storm team slip through his grasp and go to Bellamy & couldn't get a gun Souffs side a premiership, one GF with them & Ivan gets the ring. Still top 5 though.
Robbo also overrated but rounds out the 5 for lack of better options. Des would be in the discussion but loses too many points for the cap damage.
Wok, Gibson etc were at their peak before the fully professional era, so it's not a like for like comparison.
