The Kings have no need for this at all. There is plenty of offense coming from the blueline in short order. Its too expensive a luxury right now, as they are not a contender, possibly not even a playoff team.
The Kings have a ridiculous abundance of prospects, their best days are just down the road. Some fans seem to think that you need to have every single base covered and its just not true or realistic. Once they are a solid playoff team truly moving upward, sure fill a hole then. But if the goal is to compete for Cups you are going to want as many of those high-end, smart, two-way jam line drivers in your lineup as possible. That's how they'll win, not by adding a dozen goals from the left point at the expense of Turcotte, Bjornfot, Faber or Clarke - who could very well top the offense of any addition alone. Certainly not Byfield.
