Foligno-Regin-Neil was our best line in the games he played. If he's fit, he should get a look. Nothing wrong with Spezza-Turris-Regin-Smith down the middle. The young guys can compete for spots on the wing.
If Regin is healthy and playing near the top of his game how does he not make the team? he wont cost anything, can play on any line and is better than Dawg, Konopka, Condra, Obrien, Butler, and probably Greening right off the bat.
Regin has skill but he doesn't have strength. He has speed but not grit. I doubt he can play centre in the NHL although he is a pretty good playmaker but can't take a hit. Excellent speedy skater but weak on his skates, gets knocked off his skates a lot. Not sure if he is injury prone but I don't think he has completed a full season yet.
There are pros & cons to Regin's game, I see him qualified & competing with Hoffman, Filatov (if he returns), Foligno, Greening & Silfverberg for a top 6 LW spot. Or competing with Z. Smith, Zibanejad, O'Brien, Da Costa & Turris for a centre job, likely 3rd line. He has the skill, the only real question is can he take the physical play?
What I like about Ottawa's lineup right now is the combination of skill & toughness. If we were to have too many skilled players in the lineup teams like Boston would run us out of the building. With too many guys line Regin, Da Costa, Filatov, Petersson, Pageau, Silfverberg etc.. I'm afraid they won't play to the level they can for fear of being run over on every shift. We need to have the right combination of skill & toughness to be successful & defend our skilled players.
