I think games like last night are why it can be frustrating to see the suggestions to bring Beal off the bench. He's not a bench player. He is still a star level player when he's healthy. He plays within the system more than Book or KD and already sacrifices the most to make this team work.
Beal last night was better than maybe a handful of games we've seen from Grayson or Royce over the last year and change. It's not like Beal had a fantastic outing either. He played the least amount of minutes of the big 3 and didn't get a single FT. He saw 27 minutes, which was the same as Nurk for lowest amongst starters. What Beal gave us was about what we should expect when he's healthy, high IQ basketball on offense and tenacious defense.
I can understand the frustration with his health and wanting to trade him due to tax issues his contract plays part in but that's a bit different than turning him into a Sixth Man, which is below his skill level.
