With 33.3 seconds remaining in the third quarter of a two-possession game, following Malachi Flynn’s driving layup, Kevin Love got bumped into the stanchion and glared at referee Courtney Kirkland. Then Love … well … only he knows exactly what he did — and why. Cavs coach J.B. Bickerstaff, who has known Love since their early days together in Minnesota, slowly lowered his mask, shouted something in Love’s general direction and looked on in disbelief. Assistant coach Antonio Lang was flabbergasted, raising both palms and peering toward other coaches, wanting to make sure they saw the same. Brodric Thomas, an undrafted rookie free agent and one of two players waiting to receive the inbounds pass, couldn’t believe it either.
