Plenty of blame to go around but I agree that the Offensive Line with my apologies to the words offensive and line were the biggest problem and well my apologies to fat people in general for having to be associated with those fat people.
The defense for all the big plays it gave up, the plays were there to be made, Lloyd missed the sack that would’ve held USC to a FG on their 2nd TD and the Safeties (mostly Blackmon) miss played and/or miss read at least 2 deep balls that also lead to USC TD’s. If they make the play that they were in position to make the D doesn’t look nearly as bad.
