I don't really get why there's no attention being paid to his shortcomings (no pun intended).
Nobody is talking about, on the 6-yard run, when he got blasted sideways by first contact or the single-arm tackle around the shoulders that pulled him backwards. Those are just as telling about his skillset as the spin move highlight.
Not that I'm saying we should get too excited about him yet, but those things happen to every back. It's the cumulative effort that counts. Sometimes you bang into the line for 3 yards on three carries and the next carry is for 20, so four for 23 looks pretty good. Sometimes defenders whip an offensive lineman right off the snap and he's in your face and there's nowhere to go. Sometimes you juke a player out of his jock and other times the defender stays at home and blasts you when you try that spin move.
I understand what you are saying, but we can nitpick a performance to death. Vaughn rushed eight times for 50 yards (6.25 per carry) and a TD. He also caught a pass to set up the TD. That's a very good performance no matter what other professionals it came against.
Some, of course, get carried away in praising it, while others go out of their way to diminish it. I think we should recognize it for what it is and want (hope) to see more.
