So that list is 16, 15 of which are going to be in the top 25.
They also mentioned Patrick Mahomes in the same sentence as Jokic (28th) and Shohei (62nd), and since we've yet to see Mahomes on the list, he is in the top 25.
So just 9 other players one of which will certainly be Curry and probably a couple of Aaron's (Donald and Rodgers). I imagine Garnett will be there. I am curious to see if Shaq makes the list given he had a lot of time in the 90's, but his best was the early 2000's. MLB, I don't think I saw Pujols yet, not sure anyone else makes it. I don't know much about NHL, but Sid Crosby probably is there. Along with Messi, I'm guessing Ronaldo is in the top 25.
