Eagles Man Coverage - Is There Selection Bias?

Numbers would say that's not exactly true now the snaps are fewer with man but they've been the best man coverage team in the NFL this season. I think you'll see zone because I think a they'll feel better they'll feel more comfortable in zone to me like that's their like base defense now if they are in a position where they have to be in a lot of five man fronts then they're gonna play more zone right? The nice thing about playing zone coverage is it gives you the ability to double Kelsey independent of where he is so  I don't expect them to use a one double 87 call over the next two weeks.
