Starting a WR to counteract opponent's QB

I am playing in a 6 point per throwing touchdown and .5 PPR league. My opponent is starting Carr. At WR, I have Baldwin, Green, Crabtree, and Goodwin.

Should I start Crabtree to try to negate any points Carr scores?

Thanks

It is risky because, as you know, only works if Crabtree is on the receiving end of Carr’s TD. I wouldn’t sit Baldwin or Green. If you have room in your flex I think it might be worthwhile.
