Question about potential blocker or hitting receivers

[bigjohn]

this is from a fan site but a situation that is often not handled correctly.

question about the "chuck" rule. The slot receiver is 5-7 yards outside the tackle. At the snap he takes a few steps downfield and starts a crossing or drag route appx 5 yards down field. As he is crossing in front of the linebacker and looking at the QB the LB blindsides him. The QB was still in the pocket and threw the ball a second after the hit. This was done in front of the official....he saw it...looked at the downed player....no call. The receiver is out indefinately with a concussion now.

We all know there is no chuck rule in NFHS and I say any contact on a receiver like this falls under IUH on an eligible receiver. at the very least, many of these BLOCKS should be called BIB and this one possibly UR, don't you think?
