While I appreciate the reasoning behind it and personally I would love to see fewer threads on Dak and other topics that have been beat to death, but these are just phases that fans go through unfortunately.
We have had these issues with several other players, coaches and the front office in the past and the only way past them really is to let everyone get it out of their system.
If we restricted Dak threads to one thread, then you would simply see Dak discussions brought up in several other threads overtaking those threads in some cases.
At least with the Dak threads, you know which threads to avoid if you do not want to hear arguments from either side for the 100th time.
