I need help from a basketball jock

[Alex]

It's a reference to the fact that a lot of very good players have been rented by the Timberwolves.

Here's an earlier article from this same writer in which he lists the top ten performers for the Timberwolves in the last decade. On this list, Wally Szczerbiak is ranked second.

Per the introduction to this new piece, based on feedback the author has now also produced a list of the best basketball players (regardless of where they performed most of that greatness) who played for the Timberwolves in the last decade (and so if Michael Jordan had played one game for the Timberwolves in 2000 he might top the list).

From the introduction to the article you linked to:

This is the All-Timberwolves team. These are the best players to play in a Wolves uniform, regardless of amount of time.

So Wally Szczerbiak is merely an honorable mention while Al Jefferson is the decade's best power forward even though he only played a season and a half with the Timberwolves.
