I think Ace is way "less bad" to play as a SF. But since now we have both JJJ and Lauri it leaves him the only starting position as a SG, and he is a particularly bad fit for it. A good shooting guard should be very good at dribbling and decent at passing, and Ace is absolutely not there yet.You kinda oversold "how bad Ace is" in your previous post, but I think you are correct in that Ace likely wont be the 5th starter next year.
The reason isnt "Ace is bad" but its more about what we need to make the starting lineup function at the highest possible level and whether Ace provides that.
IMO our top 3 priorities for the 5th starter are POA defense, ballhandling and passing. None of those are Ace's fortes.
