On one hand you have Acy, who has shown that he can play at the NBA level. He plays with toughness, hustle, and energy every time he steps onto the floor. He's still young and has seemed to improve his jumpshot this offseason, but he doesn't project to be a player that would fit well next to Cousins as a starter.
On the other hand you have Moreland, who possess the height, length, and athleticism you look for in a running mate next to Cousins. He has the potential to be that defensive, shotblocking presence we need next to Cousins, but he hasn't shown himself at the NBA level yet.
Do you take the guy who has shown himself at the NBA level, but doesn't project to be a player that could start with Cousins or do you take the player who has the potential to be Cousins' running mate, but has not shown how his skills translate against NBA level competition?
Personally, I'll go with Moreland every day of the week. Acys are a dime a dozen in this league. Players with Moreland's potential are more difficult to come by.
