They were what they always are, very good going forward, if not quickly, but not good positioning in defence, and undone by pace.
Fortunately for them England failed generally to get round the back, but the Scots defence didn't pick up Oxlade-C for the first goal, they were like so many headless chickens for the second, and left looking at each other when Rooney scored the third. I don't mean just our two, but the whole of the Scottish defence.
There were some of the Scottish team who looked as if they hadn't recovered from their last game against the Irish. They take so much out of themselves by the amount of running they have to do forward and back. The result after 20 minutes seemed to be that England would win unless they made some mistakes, - they did once when Scotland scored. Quite simply England had too much pace and too much skill.
