"""
Get player information and stats for all seasons.
Given a player ID, such as 'BreeDr00' for Drew Brees, capture all relevant
stats and information like name, team, height/weight, career starts, single
season pasing yards, sacks, and much more.
By default, the class instance will return the player's career stats, but
single-season stats can be found by calling the instance with the requested
season as denoted on pro-football-reference.com.
Parameters
----------
player_id : string
A player's ID according to pro-football-reference.com, such as
'BreeDr00' for Drew Brees. The player ID can be found by navigating to
the player's stats page and getting the string between the final slash
and the '.htm' in the URL. In general, the ID is in the format
'LlllFfNN' where 'Llll' are the first 4 letters in the player's last
name with the first letter capitalized, 'Ff' are the first 2 letters in
the player's first name where the first letter is capitalized, and 'NN'
is a number starting at '00' for the first time that player ID has been
used and increments by 1 for every successive player.
