Dubas has no interest in helping the team that fired him. You can stop

Would getting Robertson who's 22 and Jarnkrok who's 32 not be beneficial to a team that is soon beginning a rebuild? Smith is 33 and prob won't wanna resign with PIT after next year. PIT gets Jarnkrok who's a good defensive winger and can put up 30-40 pts for 2 years. Then they can sign Robertson for as many years they want. PIT also gets a 3rd round pick and a little bit more cap space

Then Toronto gets a right shot guy who's experienced in the playoffs and can put up 40-55 points

The penguins don't want the cap of Jarnkrok who does nothing but get in the way of the younger players.
Believe me if he was that good you wouldn't be trading him.
Robinson is a future waiver wire guy, most TOR fans know this. When they needed offense and to win games, the stapled him to the bench. He'd be little more than a throw in he doesn't have much value any more than say Puustinen has for the penguins. He's a nobody and no great loss or gain.

As is PIT is better off keeping the better player of all three of these in Smith. If they do move him, it's to open up cap space. They can move him with only getting a pick back. Plenty of teams are looking for forward help. They don't need to take back cap dumps in order to move him.

Wow, that's generous offer, Pittsburgh would take it right away.
