Chicago is hiring for the margins now

Jordan Brink spent the past two seasons as the Knicks' replay challenge specialist — the person in the headset who decides, in real time, whether to burn a challenge or save it. He was good at it; the reports note an impressive success rate, including a moment in Game 2 of the NBA Finals that went New York's way. Now he's in Chicago.

It's a small hire. Worth noting because of what it signals: the Bulls are building out the operational layer, not just the roster. Taj Gibson joined the coaching staff a week ago. Now someone with a specific, demonstrable skill in a high-leverage situational role. The organization is filling in the edges.

The question the Brink hire can't answer is the one that defined last season. Chicago went 13–10 in games decided by five points or fewer — a 57% win rate in close games against a 37% mark overall. The gap wasn't about challenge decisions. It was about the 40 games that weren't close, the February that went 0–11, the roster that ran out of answers when the margin widened. Powell, Claxton, and Caleb Wilson are the bets on that problem. Brink is something else — a professional at not wasting a timeout's worth of leverage. Useful. Just not the variable that broke them.
