In betting there is the backer and the layer of the odds. If you backed £1000 at 250/1, yes you stand to win £250,000. If you use a betting exchange like Betfair, you can lay against it (acting effectively as the bookmaker) and you'll risk losing that £250,000 to win the £1000 that some think has no chance.
The person who I originally replied to said the 250/1 shot had no chance. So my comment was, would he really risk losing 250 times his stake to bet against us getting relegated at this stage of the season?
Of course, the true price is not 250/1. It's around 50/1 now after the Newcastle result. So he would *only* have to risk losing £50,000 to secure his £1,000 payout now.
Do I think we are going down? No. But there's no chance in hell I'd risk 50 times my stake to bet against it at the moment.
