Minni already has Vanek, doubt if they want another one in Kessell. Coyle and Kessell are probably not much difference production wise....I'll take Coyle and save 3.5m a year.
The trade with Kessel most likely just needs a late draft pick from 5th-7th and its a good hockey deal, especially if we get both Nino and Coyle. I personally love Coyle and Nino is fast has skill and can score.
