It has been several months since I've read the CVR transcript but my recollection is that the Captain TRIED to deploy the T/Rs but couldn't get them to deploy. If someone has read the transcript more recently perhaps they can provide more detail.
I'm thinking that the Captain may not have had the throttles all the way back against the stop which prevented the T/Rs from engaging but I'm hoping to have that either confirmed or an alternate explanation presented. The new auto-brakes procedures could certainly have contributed to the Captain not getting the motions exactly right to get the T/Rs deployed, that doesn't mean that he wasn't trying to do it.
