I don't think Nonis will blow up this team. It makes no sense. It's not like Nonis came from another organization and just took over this team now. He's been at least the assistant architect of this team under Burke, and in fact played a key role in the acquisition of many players, like Phaneuf.
I do think there are 2 main reason why he's getting very active ...
1. The changing cap ceiling and economic climate, it's an opportunity for a wealthy team like the Leafs that can absorb $$, but also a necessity for any team to make sure we manage our cap going forward in the changing economics.
2. The game 7 collapse ... you gotta think as much as Nonis tries to look at the big picture, there are things he absolutely hates in that game, and consider that a mini shuffle at the very least is required to get this team back on track.
