It wasn't in this conversation, but in a presser a couple days ago KOC mentioned that Jordan Mason was "well ahead of others" in pass protection, followed by saying this was a "big" camp for Ty Chandler, who he said needed to be more consistent. So I think we know who he meant by "others."
I'd really love to see Chandler improve as a pass blocker, because he's probably the most explosive back on the roster. If we could count on him it sure would ease my mind on the depth of the RB room.
