Not sure what you just went off on, besides that I mentioned the correlation of a #3 or #4 CB being asked to be a #1 or #2 as being similar to the WR position? Didn't mean to rehash the 2015 season because of it.
I don't doubt that guys have made the step up from being low man to high man on the totem pole. That is what happens all the time and what is expected to happen. What I was stating was to expect and rely on it to be successful every time is not realistic, especially when you are saying "The guy played great his rookie year, what happened?" and forget that the guy was playing in an easier role as a #3 CB or #3 WR and is now being asked to step up into a more difficult role. Yes, injuries play a part in performance, but as far as the CB position goes, do you think TT signs House and uses his first draft pick on King, if he is convinced that the poor play last year was just due to injuries?
