Just watching some Armstead reels on YouTube and while I understand the narrative that he’s cut in the Fournette one cut and go mold - there are some differences.

Armstead seems to be looking downfield more than looking at the next defender. Perhaps a bit more vision than Fournette in that regard. 

The other thing I’m seeing that I really like is his:
A.  Decisiveness when he sees a crease and 
B.  His ability to “get small” when he sees the slightest gap to squeeze through 
He doesn’t do the bull in a china shop routine in those spaces. He squeezes through. 
Encouraging trait.
