It's hard to believe Dawson spent so long playing with Ledley King. A centre-back who conquered his own lack of pace by reading the game becoming something of a master at the last ditch tackle.
I can only presume Dawson wasn't paying attention because he has managed to combine two major flaws.
Dawson combines being slow with sudden and dramatic loses of concentration. If he was lightening quick then his pace would rescue his lack of awareness. Alternatively, if he was able to concentrate on his positioning for 90 minutes his lack of pace wouldn't be disastrous.
As it is Dawson combines both. Opposition strikers would queue up to play against him at the World Cup.
