He's shown that he links up better, in his general play and the assists he's got with not simple passes. Adams on the other hand has repeatedly over hit passes, taken the wrong option, not made the run when players were about to play it into space...he just doesn't look on the same frequency as the rest of the team.
I completely disagree that he's shown more intelligence and works smart compared to Long. When Long came on today he won the flick on in the air and won us freekicks on a couple of occasions, and as I already said Adams doesn't seem to make intelligent runs or know where/when his teammates are going to pass it.
