It's because we actually have something to look back on ,1989 is a lot more recent than 1961, and 2005 is certainly a lot more recent than.......well never. It's called pedigree.
Yeah, Spurs have never won anything, have we? You're looking back because your present isn't very pretty, despite spending loads of money in the summer. It's called desperation.
I think you'll find that it's called "living in the past" Us Spurs fans prefer to live "in the present" because that is all that matters. And in the present, the mighty Spurs juggernaut keeps rolling on. I appreciate that that upsets you, Mickey, but you can't make an omelette without breaking an egg. Didn't you finish 7th last season? I reckon you'll get 6th this season, which is an improvement. You should be grateful for that.
I'd actually been supporting the mighty reads for about 13 years at this point, which I'm guessing is your age.
