Hmmm....
At only 24 years of age he would cost quite a bit. He had a few bad injuries this year though didn't he? Though he did look like the next big thing in 2007. Unlike Seaby he wouldn't be a "Richmond patch up" and could play first ruck for at least the next 5 years.
Our first rounder would have to be involved in the deal, and then probably a fringe player aswell. However, if a player like Vickery is still around at pick 8, it would be terribly unlucky.
Personally I would think the ideal situation would be for Carlton to use their first rounder on McIntosh meaning they don't chase Warnock leaving him four our 2nd rounder.
