That right back didn’t hold the line, otherwise Captain America would have been off.
But closer to on-topic, the biggest difference I see is the defenders take 3-4 strides until they get up to speed, in which time Christian has gained 10 yards on them. This is of course absent in FC as players approximate frictionless objects, controlled by strong magnets.
My other observation is that players move in the direction they are facing. Even in Christian’s curling, he moves in the direction he’s facing. He only curls because he’s slowly turning with each step.
This is of course basic human biomechanics, yet this has not been revealed to the team at EA.
