On one hand, it's probably meant to keep the team humble, as the wise ducks said. Appropriate fear and all that.
On the other hand, that assistant (or "staff" or whoever Harvey is talking to) has a point. This Spurs team is completely different than any team that has ever won a championship. For that reason, I've been somewhat surprised that it seems like everyone is on the bandwagon now.
I mean, yeah, the Spurs are on f'ing fire but the team's construction would shatter the championship team mold that's been around since the beginning of basketball. People could point to the 2004 Pistons but that team was totally different. They had five powerful starters who basically all played 40+ minutes when it was needed. Four of those starters were All-Star level players (Billups, Hamilton, Wallace and Wallace) and the fifth starter (Prince) wasn't far behind.
History says you either need an all-time great player playing at the top of his game or a collection of four or five All-Star level players who can play big minutes.
These Spurs are trying to win a championship with a completely different formula. They have two All-Star level players right now (Parker and Duncan) and exactly one player (Parker) who has consistently played a lot of minutes when needed. To fill the holes, the Spurs have a guy who could reach All-Star status (Ginobili), six above average players and Bonner.
I hope to all that is holy that it's enough for the Spurs to win a championship. If it is, it would be one of the most amazing accomplishments in NBA history just because it's so unprecedented.
Tbh, no championship team in NBA history is anything like these Spurs.
