I'd think a firing Fevola would be marginally more important to Geelong than a firing Bartel. But there are many what ifs in the equation.
Will Fevola ever become consistent?
Would losing Bartel leave a hole in the midfield that would make having Fevola not worthwhile as the forwards dont get enough service?
Personally I think its a bit of a myth about our midfield 'depth' we have many players in the senior team that can be rotated through the midfield, but at VFL level there isnt a lot.
If Bartel wants to go, and the Cats think that Tenace, Prismall or Shannon Byrnes can cover his loss in the midfield, so be it. They also have a first round pick which could be used on a midfielder also.
