BIB and safety

[Mike L]

in consideration of some comments made elsewhere.....

Is a BIB really a safety issue? Or is it more just an unfair blocking issue because the player has little to no opportunity to fend off the block?

Every other "safety" type foul carries a 15 penalty. The BIB used to be clipping and was essentially downgraded to what we have now, a 10 yd penalty, just like a hold and all the other blocking type fouls that I don't think anyone views as a safety issue.
How many injuries have been caused due to a BIB? I've never seen one. I suppose if the defender is standing there and the blocker blasts him from the back you could have a problem. But I'd be willing to bet 99.9% of the BIBs we see are when the blocker is beat and he simply reaches out to push the defender out of the play.
