I think Henrique would be a good match with Kovalchuk. He has similar explosiveness to his game. Henrique doesn't slow the pace down, he keeps the pace pretty high. Henrique, however, isn't as safe defensively as Josefson so there may be a few odd man rushes the other way.
I agree with this completely. While Josefson is out, I would not mind having Kovy with Henrique. I really don't like Zubrus centering Kovalchuk for some reason.
DeBoer has a lot to experiment with. There are tons of options still.
Also, I hope Tedenby gets some more time with better linemates. He is continuing to prove himself and has nothing but his size (defensive ability is still lacking but seems to be improving) holding him back.
