No you don't but there isn't a simple solution. The absolute best solution would be to give Beal lots of minutes, let him shine as a focal part of the offense and then trade him for a young player and a pick at the midseason break. The worst solution would be to give Beal lots of minutes at the expense of developing the young players only to see him falter and make him even less tradable.
I hate the idea of stretching him or buying him out but I don't know enough about the second apron to sound off either way. But IMO, if Beal really is finally healthy and if he shows he can still play, I'd give him the minutes and see what happens.
