This doesn't surprise me. From my understanding the big knock on Easton is that he doesn't handle pressure too well. Obviously that's a big deal but at the same time, it's an issue that can be corrected and if you managed to ignore that issue or presume that the issue is corrected then he looks really freaking good.
And another thing to keep in mind that most people's #2 player Tua's major issues are injury and size and those are issues that CAN NOT be corrected.
Coaches want to coach so they are going to prefer a player who has all the tools and problems that they can fix than a player with those tools but problems they can't do anything about.
