You cannot be serious. Adam is the best HEADERERERER of the ball at the club bar none. Better even than Bridcutt. He gets INSANE distance on his headers. Watch them next time. Meanwhile Greer is well known for being poor in the air for his size, he often gets "done" in the air.
Is a GOOD Championship defender, as has been forgotten in a MAHOUSIVE re-writing of history since Upson joined. Should be playing first team Championship football, no question.
Heading: Greer <<<<<<< Adam
Winding up the best player on the opposing side and nullifying them: Greer <<<<<< Adam
Clumsiness: Greer = Adam
Amazing how FEW penalties/red cards/own goals Adam gives away, considering he's apparently ALWAYS on the verge of them too.
