He has done adding talent to the roster. He hasn't "lost" a trade.
Can he be blamed for how the head coaching issues have worked out?
Yes, he can. He handed "the rope" to the third guy on our depth chart, and he asked him to do it without a safety net. The team didn't rehire Hardy's, Joe's, or Stoudamire's position.
Then, Brad made things worse by filling out the roster with unproven guys and dumpster dives, rather than giving his rookie coach some strong veteran voices in the locker room. Griffin was nice, but Vonleh and Jackson were just bad choices.
That was followed up by the team letting a bunch of TPEs expire, not filling the 15th roster spot until the brink of the playoffs, and cutting payroll during the season. I presume some of that was Wyc, even though he insists that there were no budget constraints.
I think Brad has been good overall, but he hasn't been amazing.
