if you are trading for Puka, you need to be doing so at a discount and this is not a discount if you're giving up Kenneth Walker and Trey McBride.

Elite value; trading him with Walker for Puka isn't a discount

McBride is one of the two best players in a proposed trade where he and Kenneth Walker are offered for RJ Harvey, Puka Nacua, Christian Watson, and Sam LaPorta. Trading McBride away (along with Kenneth Walker) for Puka Nacua does not constitute a discount for the Puka acquirer, even accounting for Puka's injury; holding McBride is recommended unless the Puka injury creates significant discount value.
