McVay said it in the press conference

The Rams have a very very small margin for error. When the GSOT was around Martz could care less about Warner/Bulger ints because they could overcome them. The Rams could with Goff and Stafford too. Now the Rams can't overcome mistakes. The Eagles didn't play a perfect game today but they have a large margin for error plus they are conservative enough to not give opposing teams an easy way to come back. They are smart.
