Makes sense, and I acknowledge the grey area that can be complicated to deal with. Overall it's pretty well controlled, so I'd say if a new thread pops up with which could be a duplicate, let the quality of discussion dictate the survival of the thread. overall it's not too bad, and I think anything that is newsworthy, like a big hit, suspension,injury or a nice goal, should be enough justification for a new thread. thanks. and the cleary/holland/franzen bashing is getting a bit old, whether it's justified or not imho.
In most, if not all, of these instances the duplicate threads are merged, with the one that was started first keeping the topic title (this is by default).
