Namestnikov is absolutely a player I target. Right now, the Lightning can't protect him, and even if they managed to unload Filppula, you'd imagine they'd protect Killorn over Vlad. He just seems like someone who is on the bubble of that team for some reason. He got healthy scratched recently, he's not getting protected....it all adds up. Last season, in his first full year, he was really productive in both scoring and the advanced metrics. He'd probably be able to be gotten for a fair price.
If they trade Johnson, he would be expensive to acquire. He's still an RFA too on his next contract. I don't think he makes a lot of sense, even though I'd like him. And, especially with Stamkos always in and out and being in win-now mode, I still think they do what they can to keep him (they may not be able to). But Namestnikov is a trade candidate who really should be sniffed out.
