Schaefer, but I am more confident in Misa as an elite 2C (like best in the league a la the 1/2 punch in Edmonton) than I am Smith and/or anyone else in that 5-20 range of future drafts. It is far easier to find difference making D-Men in that range than it is to find difference making centers.
13/16 playoff teams this year found their 1D outside of the top 5 of the draft. Only ones that were inside the top 5 were LA (Doughty), TB (Hedman), and FLA (Jones). 2 of those are HOFers and I don't foresee Schaefer at that level.
Schaefer projects as a backend #1 or really good #2 as opposed to a top 10 D-Man in the world. History shows that there are plenty of those guys available in the range that we're going to drafting for the foreseeable future, and Misa is a valuable enough piece to where you don't need to overpay.
If the cost is #2, #30, and #53, I am fine with that deal to move up. If it's any more than that, you're going strictly for positional need as opposed to making the highest value play (which is never wise when drafting in a non-NFL league).
