Maybe. Although I can't tell much height difference between the dude in clip 1 vs. the dude in clip 2.
One thing that I'll throw out is that in the second clip, Fillinger has an assignment--he's run a "TE" stunt with DE lined up outside him. Because of that, he knows his first move is a press, and his second move is to disengage and loop outside the end, who is crashing inside the tackle. I could hypothesize from the highlight video that Fillinger is really good when he has a specific job/stunt to perform. In times that he's asked to read and react, he is a step slower to respond, losing the benefit of his length.
Examples:
On the first clip, there's no stunt or assignment--he appears to just have B gap responsibility and, once he sees pass, he begins to pass rush. In the time he uses to react to the play, though, he stands up and runs into the guard, who he then has to press back off of himself as he makes a pass rush move.
The second clip is the TE stunt. He knows exactly what to do, and he executes it violently:
Here's some other plays from his highlights where he clearly has a rushing assignment--to show how well he plays when
Here's him running the T portion of an NT twist. Watch how well he uses his hands here to ward off OL who try to lay a hand on him:
Here, he's running a pretty simple "Blood" stunt from the B gap into the A gap. Look at how well he uses his hands here (although his pad level leaves something to be desired as he's splitting the Center/Guard):
And here are two other plays where has no obvious assignment other than to play the B-gap:
This one is against the same guy as the TE stunt. It's quintessential high school talent domination, where he runs up on the kid and presses him back.
