Booth and Mason were my favourites from the post-Fergie era. I too was gutted when Mason left, he was such a brilliant footballer. I was gutted when Booth left but very pleased when he came back for his final spell and was a much more cultured player after his European experiences.
Mackie? Paul Bernard? These are nowhere near being the worst players to pull on a Dons jersey.
I echo Dave Min's comments about it being way past the time Mackie moved on though.
