What is the value of jordan howard and Jalen Richard as a package?

I had a lot of faith in Howard like many others and took him in the 2nd. Hasn’t been turning out too well. But I just made a big trade in getting Antonio Brown but gave up 2 rbs in chubb and coleman. Do you think I could upgrade at all at rb with this package trade of howard and richard? My other rb that would start for me week 8 would be kerryon johnson (zee on a bye). Or should I just keep these 2 and hold onto hope?
