I think the Kessel trade was good for both teams.
Kessel is obviously a skilled player but wasn't working with the Leafs. I can imagine him doing well as a 2nd or 3rd liner on the Penguins.
And getting rid of him for any picks was a good move. I am glad to see the Leafs finally start to address rebuilding seriously.
The guy is one of the best goal scorers in the league and you see him as a potential 3rd liner I will almost guarantee he will be on the top line with Crosby at least initially.
