Keeper taxi Dobbins to get Henry

I could get Henry by sending Dobbins off my taxi squad.
I already have Zeke, Jacobs, Chubb.
Is it worth the Rookie loss to roster a 4th top notch RB?

Getting King Henry for Dobbins would be a massive steal.

Auction Keeper League with a taxi squad for two rookies. So Dobbins is a free keep next year.
To play King Henry with Zeke, Jacobs and Chubb. Probably still worth it.

Thanks!
