Sorry mate, but you're WAY off base here. We certainly have players in Casey that won't cut it at AFL level (like Brooks - sorry StKildonian, but if he wasn't picked THIS week, with Kosi out, he'll never play AFL again...), but Watts is CERTAINLY not one of them.
Even though I'm living in Vancouver for the year, my usual home base these days is Adelaide (my boss had a commemorative photo of '97 on his wall... pity me...). When we got Watts, all my friends who were Crows fans were lamenting it. Many of them were a little relieved when he got injured, because it stalls his progress to becoming, to their mind, one of the best full-forwards since Dunstall (they can be quite nice that way, Crows and Power fans... being glad when another team's rookie gets injured...). They really care about SANFL over there - it's a much tougher comp than the VFL and under HEAPS more scrutiny. Watts' 10 goals in that match counts for a helluva lot, along with his otherwise consistently good performances at that level.
Our team will be stronger when we, first of all, make Roo a tall running midfielder (at the expense of Fiora); and second, Watts goes into half-forward. When Gehrig retires at the end of the year, move Watts into full-forward and Sweeney into half-forward.
