Knee pop balk

[JDavis225]

How many of you guys pick this up? Obviously coaches are teaching these guys to get better at it. I've had to call it in a game before but I'm almost sure I've missed one or some too. Last night I saw Nola from LSU get away with one. ESPNU showed it in slow motion and it was pretty clear. Ole Miss's coach came out and asked the 1B guy about it but nothing came of it.  Anybody know where I can get the video?

I had to call my first one in a D2 game a couple weeks back. He picked one guy off before I finally got him. He was good at it. Coaches asked. He asked if it was because of the "knee thing"? We both laughed. Other team seemed surprised that it was actually called.

The knee pop is tough to get the first time.  I'm more successful at getting the knee pop balk when I know the guy will try it.

I got one last night. I don't think it was intentional, but it was 12-1 late in the game and I had to find something to make me earn my pay.
