Well the only one that can make you change your mind until the end of the season is DeAngelo, he has the biggest upside and he's in the NHL playing big minutes and PP. He also have the best opportunity to make room in the top 6 next year.
The other ones will not have significant role this year, they'll just continue to do well in the AHL.
I would say Honka situation is better for next year, and Theodore is not too far. Pouliot will not have buzz around him ever again... if he does that will be the next Justin Schultz in 2-3 years from now after a trade. But if you look to have a defenseman with a buzz, their value will not change this Summer compared to how poolers value them right now.
DeAngelo is the only one who fits the bill of that maybe happening.
