McKennie has misplaced passes in dangerous positions plenty of times, particularly at the start of the season and when he played in the midfield pair.
McKennie is improving every match, but at this moment it's clear Kessie is the better player. He has become very reliable playing from a double pivot, which places more overall responsibility on him, and impacts every match.
Two years ago Kessie was not the player he is today, experience helped him a lot. Hopefully McKennie has the same trajectory.
