Not sure about that. I think an assessment of the deal is more going to be determined by our finishing position. We were always going to finish above Carlton, but if we were to have had a bad run of injuries seeing us finish out of the eight (let's say 11th) then we are giving up a pick 8 for Tuohy and only getting back pick 21. Aside from it being a 13 pick downgrade, the quality of player you can pick up at 8 could be excellent. I think that's too much for Tuohy.
If we were to win the flag however this year with Tuohy (as he has been up until this point) being an important contributor then it probably wouldn't matter what pick you ended up giving up for him!
I reckon par is about a 7-8 pick downgrade, assuming the talent pool doesn't drop off a cliff in this year draft between what we would have had and what we end up with. As it stands at the moment, as
Turbocat has said, things are looking good.
