Depends on what you call talent. Mudiay has the potential to get a team 20, 5, and 5. In his entire college career WCS was slightly under productive in most categories. Mudiay has offensive tools to be a star on the right team, WCS is an upper classman role player along the lines of Chris Anderson. Both are valuable in their own way but for a team needing actual talent it would be a major mistake for the Knicks any way you slice it. Just the same it would probably be a mistake for the Kings to take Mudiay over someone like Willie.
Andersen is scrawny, not that long (6'10" with 7' wingspan), and almost all of his blocks are of flying type. WCS has a reach of 9'3", so he actually doesn't need to leave his feet to contest effectively. And WCS will have one of the best physical profiles for defensive big right after entering the league.
Also Manny is good, but not that special, but you can continue to imply, that WCS will be lucky to get second contract, while Mudiay will fight for MVP before his rookie contract ends.
