Whenever a writer or broadcaster starts a sentence by declaring that Player X (usually referring to Michael Jordan, Magic Johnson or Larry Bird) "would never have" done something that a current player (often Kobe Bryant) just did (such as taking a tough shot/"letting" his team lose a key game/shooting a low field goal percentage in a game or series/making a certain kind of mistake) you can be reasonably certain that some serious historical revisionism is about to take place.
Bird is rightly considered one of the greatest shooters of all-time and he is renowned for his ability to make clutch shots--but in his five trips to the NBA Finals Bird never shot better than .484 from the field even though he played in an era when field goal percentages were much higher than they are now. Overall, Bird shot .458 from the field during his NBA Finals career, significantly worse than his .496 regular season career field goal percentage.
In the 1981 NBA Finals, Bird's 62-20 Boston Celtics--loaded with three other future Hall of Famers (Nate Archibald, Robert Parish and rookie Kevin McHale)--needed six games to beat a 40-42 Houston team to win the championship. Bird averaged 15.3 ppg, 15.3 rpg and 7.0 apg while shooting .419 from the field. After struggling with his shot for most of the series, Bird came up big in the decisive game six (26 points on 11-20 field goal shooting, team-high 13 rebounds) but he still only ranked second on the Celtics in scoring behind Finals MVP Cedric Maxwell (17.7 ppg) and just ahead of Parish (15.0 ppg).
Although Bird later established himself as a great three point shooter, his low field goal percentage during that series was not mitigated by long range marksmanship; he shot 1-2 from three point range versus the Rockets. In fact, Bird used the three point shot very sparingly in most of his Finals appearances, shooting 4-6 in 1984, 3-9 in 1985, 7-20 in 1986 and 4-7 in 1987.
