Kevin Durant says Kyrie Irving is “frustrated” that he still cannot play Nets home games because of New York City’s COVID-19 vaccine mandate, but also thinks Brooklyn’s championship window extends beyond this season regardless of when his star teammate returns on a fulltime basis. “He’s frustrated in not being able to play,” Durant said after Monday’s shootaround. “He figured this stuff would be rolled back by now, we’d be way past this. But it’s the situation we’re in, we got to deal with it, he’s got to deal with it. Trusting that it’ll get figured out there soon. I have no clue what may happen, but I’m just trusting that things will work itself out. But I’m sure he misses playing in front of a home crowd and the home crowd, vice versa, they miss him. So hopefully we get it figured out soon.”
