The Timberwolves game was Lin's 4th game in 5 days and it was a back to back game going from playing at New York to playing at Minnesota.
I'm not going to judge Lin for a single bad performance considering the above and the first time he got any major minutes began on 2/4 against New Jersey.
Lin started with 15 points, 7/12 shooting, and 4 assists in the first half, then faded HARD in the second half due to schedule and the amount of minutes D'antoni has Lin playing because the Knicks have to lean on him in order for the current team to run well.
The kid needs some rest and he's getting some now and will bring back linsanity on Tuesday against Toronto.
Also, the most significant thing about Lin isn't his stats. It's that the Knicks are on a 5 game winning streak with no star players and bench players, and Lin is the reason why some of these non-star/bench players are stepping up and that the Knicks are playing as a team both offensively and defensively.
