We could get more than just a 7th for KOVACEVIC

No from Detroit.

Detroit passes, Our strength is at LHD, We're not surrendering that 15th overall pick for a position we absolutely don't need.

Wings pass not the right team or price

Harris might not be a good fit for sharks, plus you should at bare min get at least a 3rd for him.

Trading Matheson would be a huge mistake.

MTL loses all 4 trades you have proposed here.

Kovy gets a 3rd, Harris gets a 2nd, add an interesting prospect at minimum for Matheson, not moving 3 1sts to move up to the mid-range of the draft (also not moving Mesar to begin with or one of our decent longer term RHD options). Swap Barron and Mesar with Harris, maybe another late pick, and that's more reasonable from our end whether or not they like it is a different story but we're not severely overpaying for a mediocre improvement at draft position.
