Count where two or more columns in a row are over a certain value [basketball, double double, triple double]

I play a basketball game which allows to output its statistics as a database file, so one can calculate statistics from it that are not implemented in the game. So far I've had no problem caluclating the statistics I wanted, but now I've run into a problem: counting the number of double doubles and/or triple doubles a player made over the season from his game statistics.

The definition of a double double and a triple double is as follows:

Double-double:

A double-double is defined as a performance in which a player accumulates a double-digit number total in two of five statistical categories—points, rebounds, assists, steals, and blocked shots—in a game.

Triple-double:

A triple-double is defined as a performance in which a player accumulates a double digit number total in three of five statistical categories—points, rebounds, assists, steals, and blocked shots—in a game.

Quadruple-double (added for clarification)

A quadruple-double is defined as a performance in which a player accumulates a double digit number total in four of five statistical categories—points, rebounds, assists, steals, and blocked shots—in a game.

The "PlayerGameStats" table stores statistics for each game a player plays and looks as follows:

```
CREATE TABLE PlayerGameStats AS SELECT * FROM ( VALUES
( 1, 1, 1, 'Nuggets', 'Cavaliers', 6, 8, 2, 2, 0 ),
( 2, 1, 2, 'Nuggets', 'Clippers', 15, 7, 0, 1, 3 ),
( 3, 1, 6, 'Nuggets', 'Trailblazers', 11, 11, 1, 2, 1 ),
( 4, 1, 10, 'Nuggets', 'Mavericks', 8, 10, 2, 2, 12 ),
( 5, 1, 11, 'Nuggets', 'Knicks', 23, 12, 1, 0, 0 ),
( 6, 1, 12, 'Nuggets', 'Jazz', 8, 8, 11, 1, 0 ),
( 7, 1, 13, 'Nuggets', 'Suns', 7, 11, 2, 2, 1 ),
( 8, 1, 14, 'Nuggets', 'Kings', 10, 15, 0, 3, 1 ),
( 9, 1, 15, 'Nuggets', 'Kings', 9, 7, 5, 0, 4 ),
(10, 1, 17, 'Nuggets', 'Thunder', 13, 10, 10, 1, 0 )
) AS t(id,player_id,seasonday,team,opponent,points,rebounds,assists,steals,blocks)

Don't know if this is the best way. I first did a select to find out if a stat is double digit and assign it a 1 if it is. Summed all those up to find out total number of double digits per game. From there just sum up all the doubles and triples. Seems to work

select a.player_id, 
a.team, 
sum(case when a.doubles = 2 then 1 else 0 end) as doubleDoubles, 
sum(case when a.doubles = 3 then 1 else 0 end) as tripleDoubles
from
(select *, 
(case when points > 9 then 1 else 0 end) +
(case when rebounds > 9 then 1 else 0 end) +
(case when assists > 9 then 1 else 0 end) +
(case when steals > 9 then 1 else 0 end) +
(case when blocks > 9 then 1 else 0  end) as Doubles
from PlayerGameStats) a
group by a.player_id, a.team
