That's a part of the author's conclusion.
"With the offense in a funk the last two games, the losses piling up and playoff chances diminishing by the week, seeing Peterman play that well with most of the offensive starters still in, really showed me that the gap between he and Taylor may be diminishing."
I know the key words in the last paragraph are "may be," but his conclusion was more than just a plain no. The author added that gap qualifier at the end of his story.
And hence 13 pages on NP vs TT.
