Just say Adelaide do become interested, how about a 3-way deal where:
Bower > Adelaide
Maric > Richmond
........> Carlton
I've hit a stumbling block finding something that Richmond could offer in the exchange. Their #14 pick is too steep, #37 not enough IMO.
i think 37 is plenty but i would be taking gourdis off their hands (naturally). a 193cm, 91kg steak knife who can play key tall rather than bower's 3rd man.
