Yes. You'd be looking at a first, second, Seider or Raymond, and a roster player like Larkin. Think about what the Caps paid for Mantha. It would cost far more.
You'd create another hole by filling the center problem, in this case still in need of another top 6 C, and you'd out a big hurtin' on the farm. You can take on Okposo to get the price down, but that brings me to my next point:
Target Reinhart instead. Keep the cost down by taking Okposo's contract off their hands and it would be much cheaper than Eichel. Then we fill the top 6 center hole without selling the farm.
Have you met the New York Rangers?
