Definitely. Both he and Bear have made such a positive impact on this team. I would like to see Lagesson and/or Jones get some NHL games in this year to gauge their readiness for next year. If you could deal Russell and Benning for picks or 3rd line help then I think you have to do it because of the cap space if frees up to help the forward group out.
Ask me in 30 games, but if Bear and Persson keep up their current play I would be more than fine going into next season as this top 7D:
Nurse-Bear
Klefbom-Persson
Lagesson/Jones-Larsson
Lagesson/Jones
That gives one of the young guys a veteran partner in Larsson to break in with, and it gives you the freedom of not having to rush Bouchard if he's not ready, but also leaves the door open if he forces your hand. I personally believe Lagesson and Jones could both play bottom pairing in the NHL right now and not look out of place, and I believe Bouchard will also be ready for that next season (I personally think he could right now, but I'm more than fine with bringing him along slowly).
