I think the best lines with what we have would be:
Holland should have got a legit top line winger in the offseason. We already have two of the best centers in the league.
How many legit top-line wingers were available in the offseason? Think on it.
The answer is zero. The best wingers available were Alfredsson, Iginla, Jagr, Clarkson, Horton, and Ryder. None of them are premiere wingers. Sure, one might say that Horton could serve as one, but his contract was a giant risk given his injury history.
Dats and Z play better apart anyway. I am still surprised that they think its a good idea to play them together.
Every single bit of history disagrees with you. They play spectacularly together; when they are split up, it is almost without exception done in an effort to generate more offense elsewhere. As a duo, they are superseded offensively only by the Sedin twins, and defensively by nobody.
