One thing the NFL could take from soccer is the whole idea of a trifling foul. If the foul has no 'real impact' on the play you don't call it. If there is a hold on the exact opposite side of the field the ball is being thrown/ran to it is ridiculous for it to impact the game.
Same thing with offside in the NFL... They blow the whistle way too quick and end play. This should play advantage and give the Offense a shot at a possible big play.
