I would take pick 15 and a swap of 2nd round draft picks.
If he wants to go, let him leave.
Not to say he's overrated, but he is injury prone and I do question his longevity.
If we can end up with 3 picks in the top 30, Clark for effectively Varcoe, and hold on to Lonergan (seems more & more likely with the dramas at W.B), I'd be happy. A bonus would be picks under 50 for Hunt and/or Brown.
We haven't loaded up in the draft since 2001 and we all know how that worked out. Just hope it's as good a year as that one.
