D Holding on a CB during a Run?

[bcl1127]

I was working a youth game this weekend for 7th and 8th graders, and I was working with a non-state certified official and another one that was (yes, the youth games around here have more officials than our Freshman games). Well the wing comes in and tells the white hat that he had defensive holding on the CB on his side. Ok I thought, but then it struck me as it was a run up the middle, why would anyone call holding outside during a run up the middle? Is it even a penalty? I mean i guess it is as the guy said the CB had the WR in a bear hug, but really judgment would tell you not to flag it right? I know on a passing play if he was a receiver at the time, it would be illegal use of hands.

So am I way way way off base. I never really thought about this situation because it is something that not many people would call I would think.
