I just watched the segment, aaaaandddd...
nothing to report. Even the anchor, Kenny Mayne, was pitching the segment as "Is the Patriots' dominance bad for the NFL? I don't think so, but apparently there are some people coming up who will disagree...". Then they got to the actual segment, Trey Wingo phrased the question, starting with "in the PGA, there are two types of tournaments: the tournaments where Tiger Woods shows up, dominates, kisses a trophy at the end and walks off the winner... and then there are all the other tournaments", and proceeded to pitch the idea as best he could.
...and then Mark Schlereth and some other talking head basically competed with each other to see who could suck the Patriots' **** the hardest. They talked about how fun it is to watch this team, how compelling the quest for 19-0 is, and how much more dominant this team is than anything anyone has ever seen before. That was their answer to whether the Pats' dominance is "good for the NFL".
basically, nothing to see here. Just an ESPN excuse to see whether they could use that barb to convince some Pats fans to stay up and see if there could be anything interesting said about their team. Apparently not.
