Gurley and Lockett for Carson and Gallup?

.5 pt ppr, 10 team league, I’m currently 2-4. Team below. Thanks in advance for any advice!

Dak
Gurley
Jacobs
Julio
Lockett
Boyd (also have green on bench for when he’s back)
Herndon/Knox

I’m liking Carson over gurley because of the injures he’s had and questionable all week. But I like Lockett over Gallup

Yup I’d rather get Carson than keep Lockett and Gallup is underrated
