This game tells everything about Maguire,
he is a poor player for a team on the front foot. he is slow with the ball (which reduces the number of attacks we have and reduce the probability of us scoring), and he loves leaving his own position to charge for the ball (which fails most of the time) leaving a hole for opponents to attack. He also lacks composure and when he has 2 seconds to head a high ball to his teammate, he just randomly head it forward to let his teammates engage in aerial duels.
but when your team sits in the low block, he is the perfect player for you, making all the blocks and aerial wins.
He is a great CB for a passive/defensive team, but he is a very bad CB for a team playing on the front foot with a highline.
case closed.
