I guess i don't understand the various roles each of our RBs serve. My general assumption was that Tyree would be the change of pace, with Armstrong being the base back and Kyren Williams/Jahmir Smith roughly serving as the backups to Jafar (especially since Williams was noted for his hands and Kelly likes having an RB that can catch out of the backfield). Add to that Avery Davis and C'Bo (as speed alternatives to Tyree), and I really don't understand where Speights fits in.

To me, it seems the only back we're missing is a battering ram/Bo Scarborough/Derrick Henry back; we have 6 RBs, none of them are that and we're adding a 7th?
