They said same about Waiters as well regardless of what will be said about it now, he was 6th man etc etc.
I cant sit here and say Grant made the wrong choice he may or may not have been better off, most likely he would be in same exact spot and that is what gets lost in these conversations, IMO the player would be pretty much in the same spot, the NBA will be patient for many and let you develop, D league whatever, why not get paid for it, if you improve from 23rd to 18th on one year? Does it really matter that much.
In Tyler's case next years draft probably is much softer and he could move up by default and people are right he probably will spend some time in the D league, etc but let's see where he is at 2-3 years from now, the fact is it's probably very similar where he would be if he played one more year here or not.
