Bill Simmons often trips over his own confusion as to whether he's an entertainer or a sportswriter, but god help me if I didnt actually like his "entertaining as hell" idea for anti-tanking/the last 4 playoff teams.
Of course the dificulty would be that it might inspire MORE tanking. In other words, if eveyr tewqam, no matter how bad during the year, was going to get ot participate in a season ending mega-tourney to sneak into the playoffs, then the appropriate response would be to go ahead and lose, lose, and lose some more before said tournament, go ahead and give it your best shot during the tournament. Either sneak into the polayoffs through the tournament, or if you fall short, be lined up for a top pick. All it would really do is give the tankers a chacne to have their cake and eat it too.
