Don't really see why you felt like you needed to throw the Star comparison in there. First of all, it's a complete apples to oranges argument. 2 guys who play different positions and were expected to do different things. Also, it may suprise you that I think Ziggy has more NFL upside than Star. I do think Star is the safer pick in the sense that I don't think he has as high of a bust factor as Ziggy, but as far as what each player could become at the next level, Ziggy wins.
And for the record, I never said Ziggy wouldn't be a "good" pro. The biggest question in my mind is whether or not he's worth a pick in the top 5 or 10. He's certainly a first round talent, but he's so raw that whatever team takes him better be ready to give him a few years to grow into the type of player you draft that high. If Ziggy ends up being a bust, I think it will have more to do with the fact that maybe he's drafted by a team not willing to give him the time he needs to come into his own and then you see a coach/GM get fired, a new guy come in, and Ziggy is lost in the shuffle.
