I'm guilty of contributing. I bought my Marbury jersey over the summer to replace my Sprewell jersey.
I wear it about as often as I wear my "Fakers #8" jersey.

I love jerseys. The only problem is that they're expensive. I have Marbury's too (and Houston, Ewing, and Starks).

Vince would probably skyrocket on this list if he came to NY

This is based on the sale of Jerseys at the NBA store in NY. I figure most people that go there are Knicks fans.

It counts online sales too
