I think there's some validity to that. But bottom line: kid looks like he has elite wheels [or close to it], tremendous elusiveness, and our ST return game has lacked playmaking pop for a LONG time.
That we were able to land this kid as a preferred walk on is great roster management. You can never have enough athletes.
Please note, I'm not implying that this kid will definitely have a big impact, nor that he'll be a special teams ace in the mold of Jim Turner, Qadry, Spotwood, Harrison, or Mo Jackson. But that film suggests he's got potential. Whether he is too "small" to contribute at any other capacity beyond special teams is irrelevant to me, given that he's a walk on. We need an infusion of athletes on special teams to make our return game more potent. Hill could prove to be a steal.
Leave no rock unturned.
