Watched it over and over from that view Jamie and, whilst a headon would be more graphic ( and the stipes would have had that view at their disposal) pretty sure Lance was the main contributor to the tightening but not the only contributor. The stipes quite rightly get stuck into you for tightening in the first furlong ( 200 metres for our younger readers) or so as this is where a lot of carnage comes from.
I think someone with Lances committments is a bit of a chance at getting that penalty reduced on appeal though.
Cheers,
