I really feel like Anaheim missed out on Hall.
The argument could be made that Larsson is better/has more upside than Fowler. And I would probably agree. But I think something was there to be done unless Anaheim and Edmonton had other reasons not to deal with each other.
I think Fowler is a good top pairing right handed guy. But I also feel like he suffers from Jack Johnson syndrome. The stats aren't there for him, but watching him you can see the skill.
As for Saad, that was a win/win/win/win for everyone involved.
Columbus gets a top line winger with character and grit.
Chicago gets a suitable 2C with chemistry with Kane and Panarin and the additional piece which helped land Ladd.
Saad gets a chance to be THE guy on a team. He wouldn't get that chance on Chicago behind Toews, Kane, Hossa, Panarin, etc.
Anisimov gets to play on a top team and play with amazing linemates.
