Uwe, I think the biggest issues for many are these things
1. The bias, Perth (and other power clubs) get what they want all the time, bend little rules here and there to make it work in there favour, and i almost guarantee if it were Perth trying to bring in Harrington under the exact same cricumstances it would be allowed to happen. This is what Boty is speaking out against, mentioning Perth constantly which means they are probably the biggest culprits.
2. The problem is not the 7 games to play playoffs rule, fwiw i agree with this rule, but why does this rule stop a guy playing the remaining games of the regular season when in all likelihood the team wont make the playoffs anyway, let Harrington play the last 5 games, if they make the playoffs then he doesnt qualify, fair enough, i think the kings would accept that too and would be happy with that, as they know they most likely wont play in the playoffs, they are just trying to bring a quality player in to keep there games interesting, the crowds, sponsors, etc interested instead of fielding a sub par team due to injury which will be far less fun to watch, Harrington would atleast draw some interest among casual fans, lets see what he can do in the NBL after averaging over 10ppg in his NBA career type thing, a bit like Childress, which lets face it is far more interesting than seeing Cadee, Perry, Madgen, Garlepp, etc (all due respect to those guys) they just arnt the same draw cards.
Which is why i think most including the Kings would be happy if the NBL said, all good he can play the rest of the season, but doesnt qualify for play offs (if you happen to make it), which surely is the correct decision and isnt breaking the 7 game rule either.
3. If bringing Harrington in keeps Childress interested in sticking around longer term and even Harrington or other NBA guys interested in joining him then thats also a massive plus imo, but to see this you need to out your bias aside and not say we cant have that cos they will crush our team. Thats many peoples frustration with Perth/power teams is they are stopping things happening for other teams cos it may make it harder for there team to beat them, i see the point, but come on see the bigger picture people. Having Childress, Harrington and guys like this on any NBL team is a positive, even if he crushes your team once in a while (im a 6ers fan saw Childress crush us atleast twice, and still love that he is in the NBL). What is the negative of these guys playing NBL??? even if its just for the last 5 games on a non playoff team.
The fact they are playing the playoff teams is another reason why they should be able to replace him for the season, as they are not adding Harrington to Childress they are replacing Childress with Harrington so not really improving there squad at best its a break even move, not allowing this to happen means the Kings are going to be easy beats for the top teams, which hurts the integrity of the league imo.
Bottom line is if a ex NBA guy wants to play, is within the caps, and even say he cant play playoffs cos of the 7 games, but let him play regular season games!!
