If DR/PA/HA are all more important than IS, shouldn't they be higher? How many big men have you really seen with PA/DR/HA all higher than IS? And then you throw OD in there which you seem to agree should be on around the same level, and we are talking about a player that is extraordinarily rare and valuable. That's actually a really good SF you are describing with extra RB.
As far as free skills go, it's impossible to disagree that more is better. But almost nobody can really own players like that. I see your big men right now (the two whose builds are visible) are extremely far from that ideal. They fit my rankings much closer than they fit yours, and my players are actually closer to your rankings.
