Rotating Schedule

Basically I have 8 route and 8 drivers. Every week the route a driver has changes on a rotating schedule. The table below is an example of how it works. I creating a 1 page print out as an overview for the week to give to our dispatch and on this sheet i need to have who is on what route. I am trying to find a way to only display 1 week at a time.

My idea was to use WEEKNUM() to find the week number and then use some formula to convert that to only 1-8. For example weeks week 9 would instead be week 1 and so on. There is 2 issues with that, 1) I cant figure out the math to get that working and 2) when the year starts over you would go from 4 (week 52) back to 1 which messes up the rotation.

I am not opposed to using VBA, I just started out with formulas because i understand them a little bit better and was hoping to figure this out on my own.

Any help is much appreciated.
