My finger will be pointing at
1) Wade... has been a shell of his former self, maybe due to injury but nonetheless he has not been good for whatever reason
2) Bosh... even he agreed he was a key to the series with him matching up with the Pacers big men, but he seems weak and totally outmatched against them
3) Ray Allen... he is just not shooting anywhere near as good from three in the playoffs, its killing them
4) Battier... similar to Allen, just isn't hitting shots like he did in the regular season
I don't blame the coach, the team was playing the same style and same effort as all year the first 5 games of this series, the biggest difference is Wade is a shell of his normal self and Allen/Battier aren't hitting the open threes. Lebron and the scheme are getting these guys "their" shots but they are just missing them. I don't understand what you want the coach to do... bench Wade? but who would you play in his place that is better. Bench Bosh? Nobody better to put in there.
