Exactly.. Poe could play the Pouha position, but he certainly could play the Devito position as well. Much like Ngata. Ngata is not a nose tackle.. He plays DT in that scheme and Poe would do the same.
Wilkerson has that DE position locked up for sure.
I have to watch Poe on tape more though.. I don't care how good he is against the run, he must be a decent pass rusher as well.
