I need help answering this question 

Just prior to the broadcast of an NFL football game during the first game of the
season, a commentator states "Winning the first game of the season is of critical
importance to a team's chances of making the playoffs, as is demonstrated by the
following statistics: Last year, 62% of the teams that won their first game of the
season made it into the playoffs, while only 31% of the teams that lost their first
game made the playoffs".
Additional information
At that time there were 26 teams in the league, 16 weeks each season, with 13
games played each week. The number of teams making the playoffs was 12. Note
62% = 8/13, and 31% = 4/13. It should also be noted that making it into a "wild
card game" is considered as "making the playoffs".
Question: Do
you think there is a flaw in the commentator's statistical reasoning?
