Dumas was a huge disappointment because of what he did to his career, on the court he brought nothing but hope for the future for me. Oliver Miller, I guess he belongs in the frustrating category although he's closer to Dumas than Ayton, most of the time on the court he was a huge positive for us, it was what he did to his body in the offseason that killed us.
Bedford, Clark, Bender and Chriss should have never been drafted - I never really found them frustrating, just disappointing. I had no idea who Greg Howard was when we drafted him but I never saw anything from him on the court to raise expectations to the point where I'd call him frustrating. Jackson was frustrating, he'd show glimpses of greatness but they were never more than glimpses.
Ayton clearly has the physical gifts to become an all time great. So the fact he can so completely disappear for stretches is hugely frustrating. And his hands? If those don't frustrate you at times, consider applying for sainthood. If he was a lesser force when he was at his best, his frequent disappearances wouldn't be so frustrating.
To be clear, all of these players were frustrating in their own way but we're just talking about being frustrated by a player frequently playing below their level. And in this category, DA dominates. And we pretty much have to give him a max contract and place our hopes for the future in his hands. That's frustrating.
