Very strange group. I just hope Poles knows what he's doing.
Blackwell, Kingsley, and Sterling (not Stephen) Weatherford are all UDFA rookies. It would be especially weird to replace Sanborn with a different UDFA rookie linebacker who just got waived by another team.
Leatherwood has been discussed to death on this board, and I think the consensus is that he's basically a project at this point. I think it's really strange they picked him up on waivers given that they now have to pay him his first round pick salary. Apparently, they think they can fix him.
Wesco is a former 4th round pick TE who has potential, but hasn't been able to stay healthy. Probably a good pick up given the lack of depth at TE.
Armon Watts is a no brainer pick up at a position of obvious need at DT, so I'm glad Poles didn't outsmart himself and did the obvious thing.
