First, I will gladly trade for a young rookie center who has struggled or has issues, and/or has potential to be a #1C.
Second, I would trade for a 35+ old Veteran 1C (who is a 2c with leadership etc.)
Third, I would trade for one of Nashville centers.
Fourth, I would trade one of a number of lesser pieces for the one of the above (and draft a C) before trading Laine.
Fifth, I would trade one of Jones/Werenski for a top line center.
Sixth, try FA
All before trading for another top 6 center/winger (Domi, Roslo, Jenner even Foligno) who is going to be looking for his big long term deal that will not solve our problem with finding a Center to play with Laine.
