They are trying to trade into the top 10Using 29 on Mead is irrelevant.
They either were using that pick to match the bid, or trading it. Either way it wasn't a live pick for Port.
The big question is why did they spend their 2020 first to upgrade pick 29?
Their 2020 1st alone will likely be worth MORE than they received for the entire deal. Then they gave 29 on top of that!
Usually you give up two later picks to move up the order. Not a pick ahead of the pick you get back
