Bulls go to 3-0 on the West Coast swing but is it sustainable beyond?

Bulls coach Billy Donovan has spent the week making sure his players understand what’s sustainable and what’s not, as the Bulls start the final push for postseason hopes.

SAN FRANCISCO – Billy Donovan works from a space of transparency.

It might not always sit well with his players or even the rest of his staff, but the Bulls coach knows what winning looks like and what is sustainable.

The first two wins of this current four-city road trip? Unsustainable in Donovan’s estimation.

Sure, they’ll get away with poor rebounding nights and going after loose balls with 50% effort against the likes of the Washingtons and Charlottes, and did get away with it against Sacramento and then Utah on Wednesday night, but Donovan had bigger hopes for this roster than that.
