No. Not from either team's perspective. Gagner is an important piece for the Oilers right now. To move him for a guy who might not be any better in the future is kind of ludicrous. Cogs and the 2nd is fair for Teubert I think, although I will admit I don't know a ton about him, so my valuaation may be waaaay off.
The only situation I can see Edmonton moving Gagner for is in a package for a young 1st line centre, like Jeff Carter or someone like that. Now if the Kings were looking to move Kopitar, then we can talk, but Lombardi isn't dumb enough to move his centrepiece.
Technically, since Schenn hasn't produced anything at the NHL, then even Raitis Ivanans is more valuable than him. I don't think it is a stretch at all to consider a 5th-overall pick having the ability to put up second line center points. That is what Brayden Schenn is projected to be able to do, and that is why the Kings drafted him. The Kings have faith in their scouting department. Penner's career high of 63 points isn't a crazy number to consider Schenn reaching. Matt Duchene hit 55 in his rookie season. Schenn has three years on an entry level contract to contribute a lot of points to the Kings. Schenn will be worth a lot when comparing points per salary or cap hit.
I think Penner is a good player. I think the Kings have a similar player in Ryan Smyth. Want a deal around Smyth and Penner? That would be closer in value, though Smyth clicked with Kopitar.
Would you trade MPS or Eberle for Smyth?
Also, I'm sure Cogliano brings a lot more than his 28 points showed last season. But I bet Loktionov could get 28 points in the NHL, too.
