MIAMI GARDENS, Fla. — Kyle Shanahan will now have another Super Bowl collapse to answer questions about.

After being peppered all week by reporters seeking to rehash that blown 28-3 lead to New England three years ago when Shanahan was offensive coordinator in Atlanta, Shanahan’s first trip to the Super Bowl as a head coach ended in another late-game meltdown.

The 49ers became the third team in Super Bowl history to give up a 10-point lead in the second half when they blew a 20-10 advantage and lost 31-20.

In two trips to the Super Bowl, Shanahan’s teams have been outscored 46-0 in the fourth quarter and overtime.

Shanahan has now had seven drives as a play-caller in the fourth quarter of Super Bowls and his teams have four punts, two turnovers, one failed fourth down and only six first downs.
