Yeah but I'm thinking of how we averaged 20000 a season before moving into the 42000 SoL then averaged 41000. I remember when we struggled to get 18000 at Roker and just think that a team pushing to win the league would have 60000 easily and fans wanting more. I don't think it'll happen in my lifetime (I've not long turned 45!) but hey ho!!
Just think the demand would be massive if we were in that position.
My comment about the "capacity" was off the cuff. By modern standards, the 60000 Roker park would likely be a stadium capacity of 35000-40000 due to crushing and the regulations etc. Back in the 50s and 60s there was none of that. Plus, in my opinion, you build a stadium for your biggest attendances and we'd sell 60k against the mags easily (sadly, something I can't see happening for a while!)
