Slow day today so I watched half of Robinson's senior video. He's exactly the kind of guy that recruiting services overrate. He's huge and uses that size to push smaller defenders around at the LOS. His slow feet don't prevent him from mashing a HS DL lined up directly over him. It looks impressive when the guy is 100 lbs lighter and gets driven 5-6 off the ball. It's what you DON'T see that matters. There is only 1 highlight of Robinson locating and driving a LB flowing to the ball and nothing WRT 3rd level defenders.
But the worst part was poor balance and technique in pass blocking. Robinson repeatedly gets his weight too far forward and falls down about half the time. Since these are highlight, they only show the ones where he took the defender down with him. But it's pretty obvious there were others not seen where he missed and left the DL a clear path to the QB. In fact if you look at 5:06 that's exactly what happens when the DE beats him inside and Robinson just grabs him and throws him down.
So good: big, strong, solid HS run blocker. Bad: slow, poor balance, bad pass protector, little ability to operate in space. Looks like JAG to me.
