Agree to a point. Certainly if Miller had some playoff or championship "skins on the wall", the respect would be there. However, it's unfair to lay on this on Miller.
After all, it was Pritchard who brought the guy in, with the blessings of McMillian. It was McMillian who had been pining away for a veteran player (PG) for about 3 seasons now. In fact, upon Miller's arrival, Nate marveled how seamlessly he took over the PG duties, with very little instruction or coaching needed. Nate even hinted that he would consider loosening the play-calling reigns a bit. Of course, it hasn't happened.
Seeing as how Miller was only the Blazers 3rd choice in free agency, the fact that they signed him so quickly smacks as a desparate, face-saving move by a GM and coach, who were surprisingly spurned by two considerably, more attractive free agents.
It looks like both GM and coach failed to do their homework and examine just how Miller would fit in with their program. All of the characteristics about Miller (good and bad) are well-do ented and have been out there for years.
