I don't get the Vick comparisons other than he is black. Jackson is somewhat mobile but he's not even really considered a dual-threat QB- much less one that draws comparisons to Vick. He is a pure, pro-style, drop back passer.
Without acknowledging any differences or similarities about their play, their helmet and their built are very similar. If you were to watch the two players play on a black and white television, one may have a hard time differentiating the two of them standing under center.Having said that, Tarvaris is not the same athlete Vick is, but when Tarvaris ran the ball, he was pretty quick and pretty impressive.
