"So you're saying there's a chance?"
Actually I was wrong. I heard that on ESPN this morning and assumed they were correct. Here are the actual (but dated) stats:
Total no. of overtime games (19742003) 365
Both teams had at least one possession 261 (72 %)
Team won toss and won game 189 (52 %)
Team lost toss and won game 160 (44 %)
Team won toss and drove for winning score 102 (28 %)
Games ending in a tie 15 (5 %)
