If there's a lockout, there's no personnel transactions as PixelP mentioned, AND there's no practice, etc.
The Kings would be much more likely to end up playing abysmal ball if they haven't had the chance to reform themselves into something resembling a cohesive unit.
You do NOT want a lockout. It doesn't help ANYONE.
As far as Grant's comments go, it's June 10. There's a lot that can take place between now and midnight, June 30. The teams don't want a lockout, the players don't want a lockout and David Stern most definitely doesn't want a lockout... especially after watching what's happened with the NHL.
