I have pointed this out multiple times to Pies supporters, IRL and on BF.IIRC Stephenson was only put on the trade table (pushed) once the trade period had already started and most clubs already knew what their cap was basically going to be looking like. Not only were we one of the few that could fit him in with 0 prior planning but I think we also talked his manager and/or Collingwood into dealing exclusively with us for a few days during which we got the deal done.
They categorically refuse to look at this as one of the reasons he ended up at North.
Their narrative is that the real reason he was traded was because of off field issues, and because he had these 'issues' only 'norf' would take him on board.
The things we tell ourselves to maintain our illusions can be downright strange at times.
