A couple of important points.
1. Having Hogan would naturally straighten up the mids as they actively looked for him.
2. Tabs when he wasn't injured is one of the best contested marks in the AFL and we looked good in the first 5 rounds with him up their, A forward line with Hogan, Tabs, Cox and McCarthy playing as a wingman has a much better feel to it.
3. Langdon has played in the Pies back half because of injury problems whereas his earlier games saw him as a high HF or outside mid, I see him as another Blakely type player and that makes him a good get, being out of contract also makes him easier to pry loose. alternatively he takes Blakely's spot and we push blakely into a permanent midfield role that would involve Fyfe, Mundy, Blakely, Conca, Steve and brad Hill plus new players Cerra, Banfield and Brayshaw plus the new gun we recruit this year.
4. We improve our trade position by giving Lions Cowboy for picks 4 and 22, Then giving Demons pick 5 and next years 2nd round hick for Hogan. We trade pick 22 to Pies for Langdon and get Conca for Nixs.
5. We then use pick 4 for the best available mid in the draft.
6. Switkowski, Logue and Gero all have upside as well.
