Agreed. I think it was an honest answer to the question. Accuracy. If that's what he truly feels is most important (its way up there for me), there is no way that he can't be seriously looking to replace JB soon.
I think if Kinlaw/Brown are not BPA or are not there at 13, Blacklock wouldn't be a bad option. I'm a big fan of Gallimore, so I'd prefer him in the 2nd (if he makes it that far) over Blacklock.
I see him as a 1T that has the skill-set to generate pass rush from the 1T and could also play 3T to give us a stout IDL, while still being able to get interior pressure.
