That is a good question. If we are talking about pure on the ball defending, then no. However, his strength to his defense is something that certainly could have been used today, which is the ability to get the ball out of dangerous situations on his own with his feet. We missed that today. I don't know how much it would have helped in the end, but that was missing today.
And Rugani must either be absolute $#@!, or he did something to piss Allegri off, not to start ahead of Barzagli.
