I wouldn't be disappointed with Jones. Although I'd be happier with his teammate Telvin Smith. He's undersized (6'3, 218), which has led to some believing he's more if a safety playing linebacker, but anything I've read suggests he hits as hard as anyone and it's because of his tackling technique that allows him to make an impact against larger opponents. He's just so fast though and I guess I like the idea of a guy who can play with the range to make plays sideline to sideline.
On a side note, it's recently come out he failed a drug test, although I don't know the exact details/severity. I figure though, what the hell! Let's live dangerously once this weekend!
