A "Dangerous Scoreline"?

[Depboy]

A common comentators' cliche for a 2-0 lead, but is there any truth in it? I can see the logic in that a team leading that was leading 2 - 0 may panic after conceding and therefore leak an equaliser. Also, in play markets would surely serve to amplify any panic? An in play trading idea sprang to mind based on this premise: If a team is odds on favourite to win pre KO and goes in at half time leading 2 - 0, their odds are likely to have shortened to less than 1.09. Any 2nd half goal conceded by the favourites will cause their odds to move out to 1.15 -1.25. Even assuming no further goal is conceded, odds will stay in this range until pretty late in the game. So a half time lay would potentially give the opportunity to trade out at break even late in the game, even if only 1 consolation goal gets scored. If the favourite goes on to score a 3rd or no further goals are scored then the bet is lost, but at pretty bearable odds. Anyone see any potential in this idea?
