So that’s what it took to inspire the Indiana Pacers? Frank Vogel getting ejected? His team was going nowhere fast when the coach erupted and exited in the third quarter Tuesday night at Bankers Life Fieldhouse. Pacers point guard George Hill said his coach’s first ejection of the season showed how far their leader was willing to go to inject intensity in lackluster players.

But he ran over backup center Jeff Pendergraph and the resulting charge canceled the score. “If we would have had a game ball, it definitely goes to Pendergraph,” George said of the pivotal play. “That’s just guts, man.
