It is prudent management to have descriptions and expectations for every role you need to fill, and to find someone with the skills to fill those roles. I don't want them signing the top FA at a position because they need someone at that position.
On Ramsey, Holmes knows him as well as anyone. I presume that if Holmes thought Ramsey was the right guy for the Lions we would have heard more about the Lions' involvement in trade talks. Tweet above says Lions showed interest, but I doubt it was anything more than basic due diligence.
