As I've said elsewhere, I wasn't a fan of Raffi or Lappy. Kes and Burr were different in that they were both suspended for fractions of the times Kane and Kadri have been. Add in that Kes and Burr came through our system and not free agency in their late 20s, and they are two completely different scenarios. Also, they were dirt cheap - neither Kane nor Kadri will be.
Let other teams make those mistakes, we're been paying for our own for years already.
