[OC] 20+ years of Texans’ performance tracked via cumulative games above/below .500

I built a tool to create charts showing the cumulative games above/below a 0.500 record. I did all the NHL teams (here) and was asked a few times to do the same for the NFL. My plan is to make a chart for every team before the start of the season.

You can see all the charts produced for the NFL so far here.

Technical note: Each win moves the line up +1, each loss moves it down -1, and ties keep the value unchanged. A vertical full line shows a relocation. A vertical dotted line shows a logo change.
