I just watched Hennis' films on both BN and BSB, seven clips in all. I saw maybe three crushing blocks. Lots of soft ones. Lots of pushing without locking up his man and driving him out of the hole. Some pass "blocks" where he wasn't anywhere near a man.
I was surprised at how poorly his team ran up the middle (many losses and no-gainers); this is an indication that the interior line (including RG Hennis) simply wasn't getting the job done. At best, Hennis seemed to fall on his man, which took his man out of the play, but left the hole clogged. Compare Hennis' film to Roark, or even Akers - no comparison. Just a big kid, IMHO.
No offer, and I doubt that he will get one. A project.
