Does the visor also have something to do with the team's success? Let's go to the numbers.

Including regular season and playoff games, Pederson has worn a visor in 30 of his 39 games as head coach of the Eagles. In these 30 games, the Eagles have a record of 21-9 (3-0 in the playoffs). His go-to visors have been green or gray, but he has also worn black, and on one special occasion, his visor was white (Last season's prime-time win over the Panthers, a "Color Rush" game where the Eagles wore all white).

He wore a visor for each of his first 10 games as Eagles head coach. His first time wearing a hat was during the Eagles-Packers Monday Night Football matchup in 2016. The team wore black uniforms, so Pederson went with the black cap. That game would be the first of five straight games with a cap, largely predicated due to rainy weather. The Eagles went 1-4 during that stretch. Since the start of the 2017 season though, Pederson has had much more success in hats, going 3-1, with the most recent occurrence coming two weeks ago against the Colts.

Here's the real Eureka! moment of this investigation: The Eagles are undefeated at home when Pederson wears a visor (13-0). On the flip side, the Eagles are winless in the two road games he has worn a hat. Here's a complete record breakdown.
