So it looks like FIRST made a change to the dates of the 2020 champs.
The dates are: Houston: April 15 - 18, 2020 | Detroit: April 29 - May 2, 2020
With these new dates, Houston and Detroit have a 1-week gap in between them.
I just find this to be an interesting change with no bag day now because Detroit teams now have an extra 2 building weeks.
(Not meaning to put advantages to it just North Champs build season is 2 weeks longer)
