Yo, this Knicks/Nets crosstown rivalry is getting serious, fam! J.R. Smith called Brooklyn "the J.V. team" prior to the start of the 2012-13 season. And now, Deron Williams is pretending to take down a kid for wearing a Knickerbockers jersey?

Watch our parents residing in New York! Don't outfit your kids in apparel from either team. It's just not safe out there. 

Sidebar: Maybe a Knicks player should call Child Protective Services on Deron, you know, just to keep the feud going.
