According to Triplett Lattimore implied that it was Howden's fault but didn't come out and say it because he didn't want to throw a someone else under the bus.
And while I don't expect Howden to throw someone else under the bus, I do expect that if he didn't think it was his fault he would not say it is my fault. Instead he would have said something like it's just bad luck or they just hit on the right play call against our defense or something like that. No reason for him to take full responsibility if it wasn't his fault.
