Deserved his spot over who though? He didn't play better than Maumalo and it would be sending the wrong message if they dropped Maumalo after his effort.
I thought Ashford did a solid job on Roberts, one try came from a left edge breakaway and the other was a hail mary kick inside the 20, which if anything Maumalo shouldn't have been jamming so hard. Neither really his fault.
Yeah he basically let in that cross field kick try. But CNK was pretty shocking in defence against Dragons.
