first player to ever do that in the playoffs. i know you think stats like that are "arbitrary" but only person to ever put up those numbers in the history of the nba. thats pretty cool. he was shooting better than ive ever seen him.
I think they limit it to the last 26 years since there aren't box scores to many of the games before that.
Bob Cousy had 50 points in a 4-OT stallfest (pre-shot clock). He scored 50 of his team's 111 points, hitting 30 of 32 free throws, scoring 9 of his team's 12 in the last OT. He averaged 6.2 apg that post season, so it's possible in four overtimes he was able to get at least 10.
Edit: Here are the five playoff triple doubles from Oscar Robertson from which I have numbers (he had three more that I don't have dates or numbers to).
Oscar Robertson vs SYR 3/21/63 41 Pts 15 Reb 12 Ast W 133-115
Oscar Robertson @ SYR 3/26/63 32 Pts 19 Reb 13 Ast W 131-127 (OT)
Oscar Robertson @ BOS 3/28/63 43 Pts 14 Reb 10 Ast W 135-132
Oscar Robertson @ BOS 4/06/63 36 Pts ?? Reb ?? Ast L 120-125 (no rebound or assist numbers, but it's at least 10 and 10).
Oscar Robertson vs BOS 4/07/63 36 Pts 15 Reb 14 Ast W 109-99
Technically, using the narrow criterion of most points with at least 10 assists and 8 boards, Rondo has him beat.
Edit: Another contender that Rondo beats: Jerry West
Jerry West vs BOS 5/05/69 42 Pts 13 Reb 12 Ast L 106-108
Wilt Chamberlain's best playoff triple double was @ CIN 3/22/67 37 Pts 27 Reb 11 Ast W 123-102 (ignoring two games from '68).
