Obviously this kind of rule would never really happen. I do think the league is going in a very bad direction and the fans are paying for it right now.
We have had 2 teams completely dominate 2 rounds of playoffs. Now a 1 seed dominating an 8 seed is fine and very common, but second round series are supper to be between 2 top 4 teams in each conference. They should never ever be 2 4 round sweeps with blowouts. The Jazz at home last night were something like 9 point underdogs and 4-1 to win. To give this some perspective if the Patriots went into Jacksonville last season jacksonville would have been more like to win than the Jazz last night.
I traditionally have loved the playoffs but have felt pretty cheated this year with very of the rounds being competitive. I am sure I am not alone on this. I don't know what the league can do though.
I guess the closest thing I could see that could actually happen is limiting teams to one true max, and then having a second limit for contracts to prevent 2 top 5 players or 3 top 10 players from going together on the same team.
Also most Warriors fans soft heartedly deny this, but living in the Bay Area the enthusiasm for this years team is not what it has been the last two years. The bars have less people in them, their is little drama and the bartenders even report making less money (one of them was lamenting the sweep to me last week). People were very hyped up for the first Westbrook game and stayed that way for a quarter and a half, but then it just got pretty boring. Nobody can stay fired up watching Mcadoo, Clark and Looney closing out a 30 point game. I really think this would have been a better NBA season if Durant had either stayed in OKC (and given us another real contender in OKC) or come to Washington, Atlanta, Toronto or Boston to make the East a lot more interesting.
I really hope the next round is more competitive games or this will be the worst playoffs i can remember watching in the last 20 years.
