It seems there are a lot of misconceptions about Toronto. They are far from being the next Joe Johnson/Josh Smith/Al Horford Atlanta Hawks. And there are as many questions about other teams' futures as there are about Toronto's.
I like the Raptors a lot. I'm bullish about them.
Just pointing out, I think there are valid reasons to have some hesitancy about expecting them to not only stay at their currently level but continue improving beyond it.
Lowry should be a really good player for at least a few more years, but this is also probably going to be the best season of his career. Derozan has been in the league long enough that it's reasonable to conclude he's mostly a finished product (not a bad thing since he's pretty darn good for a non-shooting wing). I like Valanciunas, but from what I've read there are a lot of different opinions about his overall value and potential for improvement.
Worth noting, as well, that Scola and Biyombo have been really valuable bench pieces for them this year, and both are free agents this summer. They also have to make a decision about whether to bring back Terrence Ross.
Again, though ... I like the Raptors.
