Maybe I'm a pessimist but based on our last couple of season signings I'm assuming failure until proven otherwise.
Heatley, Sourray, Allen, Stoner... they were guys on the decline who were signed in hopes of a career turn around. In the case of Stoner, he had a brief time of playing adequate and was signed hoping that upward trend would continue.
Stewart can put in 15-20+ goals on some crappyears teams and has scored consistently.
He is signed for cheap, some physicality to his game which our outgoing wingers didn't have...
The guy at his current production pace would be a deal and a physical upgrade over our outgoing wingers.
And it's much more likely that BB's system sees Stewart increase his scoring like... like it does for many the players. Maybe a 2nd PP guy even.
But in the end, none of the players signed recently are 8 Stewart's ppsition. Oh.. And all those guys got pretty big multi year deals..
