I actually think this is more relevant / important than many realise. Yes Emerson's crossing was terrible yesterday, and Adama's normally is too. However, Emerson was usually crossing from poor positions because he was either unwilling or incapable of beating his man. Adama would simply have smashed his way past that man to the byline, and hopefully smashed a random ball across a dangerous area. So whilst they are both poor at passing / crossing generally, Adama's ability to easily get into a better position would (for me at least) have made him more likely to create a goal.
Before anyone says it, I know Adama has no assists this season - it's not as though Emerson looked like a world class deliverer of the ball yesterday either, but at least at Spurs Adama would have lots of better targets to aim for. In any case, for me it's not games like yesterday's where Adama would be the greatest asset - it would be games where we are under lots of pressure. His ability to get you 30 yards up the pitch when you're under pressure would be godsend against some of the better sides..
