I think he slid so far down in the draft because GMs thought that his absolute ceiling would be the numbers that he wound up putting up this year. I'm not ready to put a lid on anything because of that. He's already far surpassed expectations and he's only 20.
I still have him as a Joe Ingles type player and I don't think he'll ever be what Edwards and Ball will probably wind up being but that's perfectly ok because we weren't picking 1st or 3rd so we didn't have a chance at those guys anyway. He's actually better than Edwards right now but you can see Edwards has a brighter future as a #1 option.
@D13 made some good points in this thread. Why not let Hali push it more so we can see what he can and can't do? I'm not a big fan of throwing players to the wolves (no pun) because it can certainly hurt their confidence if they fail miserably at it but I'm also not a fan of locking young promising players into narrowly defined roles that might bring out the best in them at the time, but fail to unlock the ability to hit their ceilings in the future.
Problem is that Walton is the coach and he's going hard after pointless wins right now to make himself look better. It's hurting the development of players and the future of the franchise. Haliburton is just one of many players that are being hurt by his selfishness.
