This reminds me of the Stephon Marbury situation from last year's Playoffs. People were saying that he had a chance to win a game for us or at least create an offensive spark.
IIRC, during Game 5 of the Magic series, we were tied with the Magic at 2 games apiece in the series and we were down by a significant amount of points. Doc hadn't put Marbury in too much prior to that game, just like with Nate-Rob, but out of desperation, he decided to sub him in for Rondo (I think). Like people had predicted, Marbury scored 12 points in the quarter to give us the lead, and ultimately, the win. Eventually, we ended up losing that series, but the point is, I feel the Robinson could have a similar, if not, an even bigger impact than Stephon Marbury had on that game.
Unlike Starbury, however, Robinson is lightning-quick and gives us a little production on the defensive end.
