Rookie Draft 1.01 with Brown on roster

I have the 1.01 in a rookie draft. I also already have Antonio Brown on my roster. With the Raiders not figuring to have a great offense should I still go Josh Jacobs at the 1.01 even with already having AB or go with Montgomery? Also thought about trading back a few spots and picking up an extra pick later on and taking Miles Saunders. Any thought? Suggestions? Ideas?

I’d still go Jacobs, raiders offense should be much improved and Jacobs will feature as a workhorse back fo years to come
