From my view in Sect 202, I don't think the refs had a great game. Better? Maybe, but that is a low bar to clear. I'll have to re-watch the broadcast at some point to make a better judgement than row S in the second level.
I don't think Clingan is playing enough. On the other hand, I think Hurley has improved his early game substitution patterns. I mentioned this elsewhere as well, but at the tail end of the win streak and at the beginning of the skid, the starters would generally play at least the first 8 minutes and often over 10.
It might be anecdotal, because I haven't dissected (and don't plan to) all of the previous play-by-plays, but it seems the bench is being used earlier. For instance, last night. Clingan and Alleyne came in inside of 6 minutes, followed closely by Joey C. I recall this happening the last handful of games.
I also think that either Jackson or Hawkins (or both) need to be on the court at all times a la Jordan and Pippen. Jackson is not a scorer but he is a prime facilitator.
