Does Shielding even work in this game????

I noticed everytime I have the ball, opponents are just able to run at speed in behind my player and just take the ball very easily, even if I shield, so there is no physics whatsoever, my player is just non existent, which seems to be a meta type of thing where you can just run at full speed at somebody and just take the ball even from behind so they removed bruiser but I still see alot of bruiser type of stuff happening. and its only in Ultimate team, in seasons, it doesn't happen like that, the normal shoulder to shoulder mechanic works, but ultimate team is just broken.
