I see David Elleray (former referee) is renewing calls for sin-bins in football. Do you agree?

Personally speaking I don't, and here's why...first of all in football, it's very easy to deny a team posession, so if a team know they're down to 10 men for, say, 5 minutes then their first reaction will be to simply get the remaining players behind the ball and ironically teams a man up will be less likely to score. Sin-binnings would very quickly become something that completely kills the flow of a game (probably also the in-stadium atmosphere as the supporters realise they've got 5 minutes to go to the loo or get a pie.)

And also, the player who gets sin-binned is getting a breather, so imagine him coming back on the field and right away making a lung-bursting run to skin a tired defender and score - who's really been penalised then?
