Start Andrews as a flex? PPR

I was able to keep Ertz last year and picked up Mark Andrews for giggles. Andrews seems to be the #1 target on the Ravens and Ertz is Ertz (especially with 3 pass catchers out). Is Andrews flexible over MJones, Mike Williams, Breida, and Shepard (if he plays)?

It’s not my favorite thing to do as far as roster construction/flexibility but I absolutely would considering the numbers Mandrews is putting up and the extra targets coming Ertz’s way with all the WRs hurt.

It’s not something I would do week -to-week but I can see arguments for it from time to time during season, especially once byes start.
