[Python] Create a True/False column based on a sequence of numbers in another column with...

I want to add a Momentum column to my df that takes True when I have three or more consecutive possessions and False otherwise.

I have this:

event seconds_since_start_of_game possessions
FOUL_RECEIVE 49.0 1.0
FOUL_RECEIVE 73.0 1.0
POST_OUT 86.0 1.0
LOST_BALL 101.0 1.0
2MIN_PROVOKE 122.0 2.0
FOUL_RECEIVE 137.0 2.0
POST_OUT 148.0 2.0
POST_OUT 306.0 4.0
LOST_BALL 324.0 5.0
FOUL_RECEIVE 362.0 6.0
LOST_BALL 376.0 6.0
FOUL_RECEIVE 399.0 7.0

event seconds_since_start_of_game possessions momentum
FOUL_RECEIVE 49.0 1.0 False
FOUL_RECEIVE 73.0 1.0 False
POST_OUT 86.0 1.0 False
LOST_BALL 101.0 1.0 False
2MIN_PROVOKE 122.0 2.0 False
FOUL_RECEIVE 137.0 2.0 False
