Winning the lottery is a huge risk as it requires tanking and luck
. And some elite players moved in free agency/trades before they won their first title (Shaq, KG, Allen, Gasol, Lebron, Bosh, Kidd, Drexler for example).
So there is some merit in waiting for the elite talent to come to you, and with Wiggins there is a good chance that he would want to come back home.
However just because he's Canadian means jack sh!t these days. Nash burned us to play for the Lakers and was offered $12M a year at the age of 38.
So either way it's a gamble
. The problem is that the Raptors need talent badly. So even if they don't get Wiggins there are a lot of potential studs in the 2014 draft that could end up being elite. So from that perspective taking for '14 still makes a lot more sense.
