Gary,
That patch looks ok from those cards I have seen. There was a Ewing Limited Logos card from the same set (Graded by BGS) a while back that had a fake patch placed in it but the patch was a piece that Ive never ever seen on a Knicks jersey.
yeah we have proven in the past that BGS grade cards with fake patches in them. The numbering on cards these days makes it easier to catch the cheats ;-)
