Yes, but if Borough had won - and with a serious chance of getting three points next week too - B'mth would be under pressure to win both matches. Now B'mth can afford to draw one, and still go up; much less pressure, especially if they despatch Bolton tomorrow, which is very likely. As I said...
Why did Boro send their keeper up in the last minute?
Obvious really. One point wasn't realistically going to keep them in the hunt for automatic promotion, only a win would do.
