I absolutely agree, the Bills had way more pressure on them at the half in that game than the 10-3 cruising in first place Vikings had. The Bills were about to knocked out of the playoffs and were being absolutely embarrassed and outclassed. The Vikings comeback is impressive but they would not have been able to do it against a team of the Oilers calibre of 92!
As for your last line, unfortunately such things are inevitable. People will never know or appreciate the context if they didnt watch it live or in person and realize what an impossible situation the Bills were faced with at the half and the miracle that ensued!
