Value aside the jackets should stay the course and rebuild the right way. We’re basically swapping gavrikov and nyquist out for better players at the cost of 3 first round picks and a second.
IMO this is an overpay by the jackets, especially given the fact that they are still rebuilding. Giving up that many young assets would destroy the rebuild. Also at that caphit I don’t know if Keller is worth even targeting for the jackets.

Honestly I wouldn’t make this trade if I were Columbus, value is probably correct, just not the right timing for Columbus who still needs a 1C badly.
