1) I have no problem with Armstead competing in practice for a roster spot over 2-3 weeks.
I just don't think that he'll beat out Vellano. My personal expectation is that he will end up on IR.
Agree completely, I have never heard of a player with no NFL experience and who hasn't attended one practice being activated halfway through a season. Had Armstead been practicing since eligible I could see it being discussed but he isn't even ready to start practicing. His best bet is IR and another shot next year.
