I get being a Minnesota fan makes my input optically poor, but no, it isn't even close.
During that WCF run, the Timberwolves had
Sam Cassell's back and hip implode from an injury,
Wally Sczcerbiak had to play through three cracked vertabrae, Gary Trent was cooked from lingering ankle injuries,
Troy Hudson (backup PG) was out-for-the season because of an ankle injury,
and Ervin Johnson (starting Center) was playing through a wrist injury.
Starting PG crippled, backup PG deleted from the roster, best wingplayer playing through a broken back, backup SG hobbled, and starting Center hobbled. Darrick Martin was functionally their only Point-Guard, which is frightening.
Because of this, Kevin Garnett had to transition into being Minnesota's Point-Guard because Latrell Spreewell was terrible and nobody could dribble the ball up the court. Additionally, Minnesota ran a point-of-attack 1-2-2 zone defense with Kevin Garnett where he would (I mean this literally) have to roam around the entire court as the guy who picks up the ball and operate as the helper. When Minnesota needed him to play big, they would transition to a 1-3-1 zone where he would play the same role, except instead of being at point-of-attack, he would start under the basket.
This all means that Minnesota's 6'13" Power-Forward had to be a defacto Point-Guard to dribble the ball up the court, carry the majority of Minnesota's scoring/facilitating load, and was the team's only positive impact defensive player who the entire defense leaned on. I cannot overstate how unbelievably ridiculous that series is to watch, to the point where it should settle any conversation about Latrell Spreewell not being a disaster.
TL;DR: Comparing those two situations (especially with the massive differences in pace of play) is straight up wrong.
EDIT: An example of the extent of the trainwreck was Minnesota losing 92-85 in Game Four of the Western Conference Finals when Kevin Garnett played 47:29 (no, the game did not go to overtime) and dropped 28-13-9. He scored or assisted on 56.5% of Minnesota's points, and they still lost the game. Legitimately tragic, it's ridiculous that Minnesota lost in six by a cumulative margin of only thirteen points.
