Well multiple insiders right around 3 said it may well happen, didn't hear who and later it came out it was supposedly Larsson
The guy who mentioned Larsson's name has as bad of a rep as Eklund, I wouldn't take that rumor to seriously, especially since the much more credible insiders on TSN has already shut the Larsson for Brown rumor down. Still, that the Oilers are very much interest in Brown is pretty legit, the TSN guys believe that Benning for Brown has been discussed, and Khaira and Kassian's name have also been mentioned. My guess is Khaira is probably the guy the Leafs were targeting as he could probably be signed for at least 1 mill less than Brown in the offseason and he can bring size and toughness to the bottom 6, while still possessing the speed to keep up with this Leafs' brand of hockey, his injury probably dissuaded the Leafs however.
Benning thou is likely the guy the Oilers wanted to trade, as the Oilers has finally gotten Sekera back and a couple of their D prospects are almost ready to play on their team. Can't see what the Leafs would want with Benning thou, as Oilers fans seems to have a very low opinion of him.
