Is this Deal Veto-able

14 team Superflex league with two flexes, PPR scoring.

Team A which is in the playoffs gets CMC plus Bryce Young

Team B which has been eliminated, gets Jacobs, Christian Watson and Tua. This team just traded for CMC, right before his bye week (he gave up James Cook and Jeanty for him) even though he still had a 20% chance to make the playoffs.

First question, who gets the better of the deal?

Second question, is the trade veto-able?
