I don't see why Blake can't score 40 again, he's playing with pretty much the same caliber team, and he has Mats to set him up. As for Toskala, I'm sure he'll take advantage of this oppertunity, he has to prove himself somehow (hopefully he'll do it in T.O.)
Things like this are tricky to answer because of all of the "what if's". Personally I think Blake will have a good year, but nowhere close to last year's performance. I could see him playing horribly this year because of the pressure and everyone will be like "Nice waste of four million dollars". Mark my words, Jason Blake will under acheive this comming year. But watch him get back to back 30+ goal seasons after this.
Toskala will no doubt try and impress Leafs Nation. He is a much needed boost from Raycroft but I think Raycroft would have a better year this year then last. I think that Toskala and Raycroft will share duties until the 40 game mark then a definative #1 goalie will be chosen.
