I don't think he played badly at all. It is just I don't believe in similar CBs pairing. You need different type. It looks worse that he can't really pass forward and it puts so much pressure on whoever he is passing who will have to stay back within 5 yards of him.
So many times today, both of he and bailly passed to our FBs who was staying pretty deep and they immediately got pressed and lost the ball a few times or just had to turned back and passed the ball to keepers.
At least with blind, shaw can stay a bit higher to make sure the other team has to worry behind their line and blind would beat the line 8 out of 10 times.
