You guys don't watch Basketball. Those early Dallas Teams were TERRIBLE. Dallas was a poorly ran Organization that botched all the Top Talents they had at that time. Anyway...
Jason Kidd goes to the Nets, one of the Youngest and Inexperienced teams in the NBA, and leads them to the Finals his first Two Seasons (Runs into Shaq & Kobe and then Duncan & Robinson). You need to know the Nets had ZERO Championship aspirations by the Media when NJ got him. Of course things changed. They had no answer to slowing down Shaq at all, but against the Spurs, the Nets were up by 8 in the 4th Quarter of Game 6, could've forced a Game 7 had they made better Defensive Coaching Decisions.
New Jersey refused to pay Kenyon Martin in 2004, and that was the downfall for the Nets as Championship Contenders from then on. Kidd, Carter and Richard Jefferson did the best they could without any help from the Bigs on their teams.
And that Game 7 Loss you bring up, that was actually a Choke Job by the Nets, as they were up by I believe 20 in the 1st Quarter. Just didn't have an answer for Detroit's Bigs.
And Kidd had MANY games where he missed Triple-Doubles because he had Single-Digit Points, because he simply didn't take a lot of shots. Later in his Career, well past his Prime, he almost had a 20/20/20 Game.
Easily one of the Greatest Players of All Time.
