McKenna,Donaghy and Cavanagh in my opinion have been the 3 best midfielders I have seen playing for Tyrone.Both Eugene and Plunkett were better fielders and could also play a bit too,they weren't just one trick ponies.Cavanagh's biggest strength is his running at defenders which he could do from no.12 as well.
If I had to pick one between Donaghy and Cavanagh(which I didn't have to) I would pick Sean but I put him at wing forward.Simple really.
Anyway keep your hair on,it's not like we're going to send this team out to play a game!!
