i can't comment on Sat as didn't see anything.
As a general comment though, only on the rarest of occasions have i ever felt i was genuinely at risk of getting dragged into bollocks with opposition fans. From my experience, those that do, tend to contribute to the situation kicking off. I wonder how much sympathy I'd get if i walk down Penistone Rd next Sunday indiscriminately offering folk out and end up listening to the match in Northern General? Fck all I imagine.
Walking out of Reebok on Tues and some young and giddy Blades (16 at most) were chanting 'easy'. They quickly attracted some 'fck off ya yorkshire bastards' comments and for a moment I thought there could be a bit of bother. As it was pissing it down and the kids immediately shut up, nothing kicked off.
If you take responsibility for your own cocking about behaviour, chances are you'll always be fine. If you fancy exchanging blows with fellow knuckle draggers then crack on, I couldn't give a shit.
