Lest pull those with ADD, back into context.
This started with the unsubstantiated opinion that the gospel text have undergone UNKNOWN extensive evolutionary changed after their initial compilation.

Autographs and first copies may well have remained in circulation until the end of the second century, even the beginning of the third century…The longevity of these manuscripts in effect forms a bridge linking the first-century autographs and first copies to the great codices, via the early papyrus copies we possess (35).
In other words, it is possible (and perhaps even likely) that some of the earliest copies of the New Testament we posses may have been copied directly from one of the autographs. And, if not the autographs, they may have been copied from a manuscript that was directly copied from the autographs. Either way, this makes the gap between our copies and the autographs shrink down to a rather negligible size.

Since we don’t have the originals, and only copies of copies of copies, then who knows what the text was really like before our extant copies were made.
So here we have two credible scholars, but they are not making opposite example's. One states we don't know, and the other they probably stayed the same.
To go out on a limb as Stephan has and say they changed dramatically requires more then unsubstantiated rhetoric
