The Oklahoma City Thunder have been mounting ferocious comebacks all season long, but they were in danger of blowing a big lead of their own.The Thunder had trailed for most of three quarters before hitting the gas and dominating the fourth in Toronto last Wednesday, Dec. 8. They turned a 13-point deficit into a 14-point lead with 6:13 left in the ballgame, up 97-83.But then, disaster: Justin Champagnie scored an and-one layup and jump-started Toronto’s offense just as OKC went cold. With just under 1 minute to play, Fred VanVleet nailed a 3 – Toronto’s third in three possessions – to knot the score at 105.
