TV revenues weren't the same then, the Champions League didn't exist in the way it does now and we regularly got 8,500 average where as Celtic couldn't fill up Hampden when they rented it. We were much closer to them then compared to now.
Bosman and Euro runs beyond Christmas is what opened the gulf and our dwindling attendances because people looked for alternatives to spend their money on.
I can't think of where we'd pick players up from but it certainly wasn't Forest Green Rovers and alike.
We now have a mindset against the OF which isn't shared by a few other teams in the league (Killie and ICT being two standouts with budgets around our level or less). The 20 year league thing against Rangers is quite a noose round the neck until you remember they've had "The" in front of their name since 2012.
I just wish we'd actually show up and give them a game more often than we do.
